Revision history for indirect
+0.12 2009-05-03 14:30 UTC
+ + Add : You can specify the action to execute for each indirect
+ construct encountered with the new "hook => $coderef" unimport()
+ option.
+ + Chg : A ptable is now used internally for the op => position mapping.
+ + Fix : The pragma is now built with thread safety features enabled
+ whenever possible (a notable exception is perl 5.8.x on Win32,
+ as something seems wrong with its context handling).
+ The new indirect::I_THREADSAFE() constant reflects this.
+ + Fix : A negation precedence nit in indirect_ck_entersub().
+ + Tst : "use/no indirect" while parsing an indirect construct.
+ + Tst : Thread safety.

+ Fix : Potential collisions by hashing pointers with a wrong format.
+ Upd : Resources in META.yml.

SYNOPSIS
+ # In a script
no indirect;
my $x = new Apple 1, 2, 3; # warns
{
use indirect;
my $y = new Pear; # ok
+ {
+ no indirect hook => sub { die "You really wanted $_[0]\->$_[1]" };
+ my $z = new Pineapple 'fresh'; # croaks 'You really wanted Pineapple->new'
+ }
}
no indirect ':fatal';
if (defied $foo) { ... } # croaks, note the typo
+ # From the command-line
+ perl -M-indirect -e 'my $x = new Banana;' # warns
+
+ # Or each time perl is ran
+ export PERL5OPT="-M-indirect"
+ perl -e 'my $y = new Coconut;' # warns

DESCRIPTION
When enabled (or disabled as some may prefer to say, since you actually
turn it on by calling "no indirect"), this pragma warns about indirect
This module is not a source filter.
METHODS
- "unimport @opts"
+ "unimport [ hook => $hook | ':fatal' ]"
Magically called when "no indirect @opts" is encountered. Turns the
- module on. If @opts contains ':fatal', the module will croak on the
- first indirect syntax met.
+ module on. The policy to apply depends on what is first found in @opts :
+
+ * If it's the string ':fatal', the compilation will croak on the first
+ indirect syntax met.
+
+ * If the key/value pair "hook => $hook" comes first, $hook will be
+ called for each error with the object name as $_[0] and the method
+ name as $_[1].
+
+ * Otherwise, a warning will be emitted for each indirect construct.
"import"
Magically called at each "use indirect". Turns the module off.
+CONSTANTS
+ "I_THREADSAFE"
+ True iff the module could have been built when thread-safety features.
+
CAVEATS
"meth $obj" (no semicolon) at the end of a file won't be seen as an
indirect object syntax, although it will as soon as there is another
