2 indirect - Lexically warn about using the indirect object syntax.
9 my $x = new Apple 1, 2, 3; # warns
12 my $y = new Pear; # ok
15 if (defied $foo) { ... } # croaks, note the typo
18 When enabled (or disabled as some may prefer to say, since you actually
19 turn it on by calling "no indirect"), this pragma warns about indirect
20 object syntax constructs that may have slipped into your code. This
21 syntax is now considered harmful, since its parsing has many quirks and
22 its use is error prone (when "sub" isn't defined, "sub $x" is actually
23 interpreted as "$x->sub").
25 It currently does not warn when the object is enclosed between braces
26 (like "meth { $obj } @args") or for core functions ("print" or "say").
27 This may change in the future, or may be added as optional features that
28 would be enabled by passing options to "unimport".
30 This module is not a source filter.
34 Magically called when "no indirect @opts" is encountered. Turns the
35 module on. If @opts contains ':fatal', the module will croak on the
36 first indirect syntax met.
39 Magically called at each "use indirect". Turns the module off.
44 XSLoader (standard since perl 5.006).
