+NAME
+ Variable::Magic - Associate user-defined magic to variables from Perl.
+
+VERSION
+ Version 0.01
+
+SYNOPSIS
+ use Variable::Magic qw/wizard cast dispell/;
+
+ my $wiz = wizard set => sub { print STDERR "now set to $_[0]!\n" };
+ my $a = 1;
+ cast $a, $wiz;
+ $a = 2; # "now set to 2!"
+ dispell $a, $wiz;
+ $a = 3 # (nothing)
+
+DESCRIPTION
+ Magic is Perl way of enhancing objects. This mechanism let the user add
+ extra data to any variable and overload syntaxical operations (such as
+ access, assignation or destruction) that can be applied to it. With this
+ module, you can add your own magic to any variable without the pain of
+ the C API.
+
+ The operations that can be overloaded are :
+
+ "get"
+ This magic is invoked when the variable is evaluated (does not
+ include array/hash subscripts and slices).
+
+ "set"
+ This one is triggered each time the value of the variable changes
+ (includes array/hash subscripts and slices).
+
+ "len"
+ This magic is a little special : it is called when the 'size' or the
+ 'length' of the variable has to be known by Perl. Typically, it's
+ the magic involved when an array is evaluated in scalar context, but
+ also on array assignation and loops ("for", "map" or "grep"). The
+ callback has then to return the length as an integer.
+
+ "clear"
+ This magic is invoked when the variable is reset, such as when an
+ array is emptied. Please note that this is different from undefining
+ the variable, even though the magic is called when the reset is a
+ result of the undefine (e.g. for an array).
+
+ "free"
+ This last one can be considered as an object destructor. It happens
+ when the variable goes out of scope (with the exception of global
+ scope), but not when it is undefined.
+
+ To prevent any clash between different magics defined with this module,
+ an unique numerical signature is attached to each kind of magic (i.e.
+ each set of callbacks for magic operations).
+
+CONSTANTS
+ "SIG_MIN"
+ The minimum integer used as a signature for user-defined magic.
+
+ "SIG_MAX"
+ The maximum integer used as a signature for user-defined magic.
+
+ "SIG_NBR"
+ SIG_NBR = SIG_MAX - SIG_MIN + 1
+
+FUNCTIONS
+ "wizard"
+ wizard sig => .., data => ..., get => .., set => .., len => .., clear => .., free => ..
+
+ This function creates a 'wizard', an opaque type that holds the magic
+ information. It takes a list of keys / values as argument, whose keys
+ can be :
+
+ 'sig'
+ The numerical signature. If not specified or undefined, a random
+ signature is generated.
+
+ 'data'
+ A code reference to a private data constructor. It will be called
+ each time this magic is cast on a variable, and the scalar returned
+ will be used as private data storage for it.
+
+ 'get', 'set', 'len', 'clear' and 'free'
+ Code references to corresponding magic callbacks. You don't have to
+ specify all of them : the magic associated with undefined entries
+ simply won't be hooked. When the magic variable is an array or a
+ hash, $_[0] is a reference to it, but directly references it
+ otherwise. $_[1] is the private data (or "undef" when no private
+ data constructor was supplied). In the special case of "len" magic
+ and when the variable is an array, $_[2] contains its normal length.
+
+ # A simple scalar tracer
+ my $wiz = wizard get => sub { print STDERR "got $_[0]\n" },
+ set => sub { print STDERR "set to $_[0]\n" },
+ free => sub { print STDERR "$_[0] was deleted\n" }
+
+ "gensig"
+ With this tool, you can manually generate random magic signature between
+ SIG_MIN and SIG_MAX inclusive. That's the way "wizard" creates them when
+ no signature is supplied.
+
+ # Generate a signature
+ my $sig = gensig;
+
+ "getsig"
+ getsig $wiz
+
+ This accessor returns the magic signature of this wizard.
+
+ # Get $wiz signature
+ my $sig = getsig $wiz;
+
+ "cast"
+ cast [$@%&*]var, $wiz
+
+ This function associates $wiz magic to the variable supplied, without
+ overwriting any other kind of magic. It returns true on success or when
+ $wiz magic is already present, and false on error.
+
+ # Casts $wiz to $x
+ my $x;
+ die 'error' unless cast $x, $wiz;
+
+ "getdata"
+ getdata [$@%&*]var, $wiz
+
+ This accessor fetches the private data associated with the magic $wiz in
+ the variable. "undef" is returned when no such magic or data is found.
+
+ "dispell"
+ dispell [$@%&*]variable, $wiz
+ dispell [$@%&*]variable, $sig
+
+ The exact opposite of "cast" : it dissociates $wiz magic from the
+ variable. You can also pass the magic signature as the second argument.
+ True is returned on success, and false on error or when no magic
+ represented by $wiz could be found in the variable.
+
+ # Dispell now
+ die 'no such magic or error' unless dispell $x, $wiz;
+
+EXPORT
+ The functions "wizard", "gensig", "getsig", "cast", "getdata" and
+ "dispell" are only exported on request. All of them are exported by the
+ tags ':funcs' and ':all'.
+
+ The constants "SIG_MIN", "SIG_MAX" and "SIG_NBR" are also only exported
+ on request. They are all exported by the tags ':consts' and ':all'.

+
+=head2 C<gensig>
+
+With this tool, you can manually generate random magic signature between SIG_MIN and SIG_MAX inclusive. That's the way L</wizard> creates them when no signature is supplied.
+
+ # Generate a signature
+ my $sig = gensig;
+
+=cut
+
+sub gensig {
+ my $sig;
+ my $used = ~~keys %wizz;
+ croak 'Too many magic signatures used' if $used == SIG_NBR;
+ do { $sig = SIG_MIN + int(rand(SIG_NBR)) } while $wizz{$sig};
+ return $sig;
+}
+
+=head2 C<getsig>
+
+ getsig $wiz
+
+This accessor returns the magic signature of this wizard.
+
+ # Get $wiz signature
+ my $sig = getsig $wiz;
+
+=head2 C<cast>
+
+ cast [$@%&*]var, $wiz
+
+This function associates C<$wiz> magic to the variable supplied, without overwriting any other kind of magic. It returns true on success or when C<$wiz> magic is already present, and false on error.
+
+ # Casts $wiz to $x
+ my $x;
+ die 'error' unless cast $x, $wiz;
+
+=head2 C<getdata>
+
+ getdata [$@%&*]var, $wiz
+
+This accessor fetches the private data associated with the magic C<$wiz> in the variable. C<undef> is returned when no such magic or data is found.
+
+=head2 C<dispell>
+
+ dispell [$@%&*]variable, $wiz
+ dispell [$@%&*]variable, $sig
+
+The exact opposite of L</cast> : it dissociates C<$wiz> magic from the variable. You can also pass the magic signature as the second argument. True is returned on success, and false on error or when no magic represented by C<$wiz> could be found in the variable.
+
+ # Dispell now
+ die 'no such magic or error' unless dispell $x, $wiz;
+
