NAME indirect - Lexically warn about using the indirect object syntax. VERSION Version 0.08 SYNOPSIS no indirect; my $x = new Apple 1, 2, 3; # warns { use indirect; my $y = new Pear; # ok } no indirect ':fatal'; if (defied $foo) { ... } # croaks, note the typo 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 object syntax constructs that may have slipped into your code. This syntax is now considered harmful, since its parsing has many quirks and its use is error prone (when "sub" isn't defined, "sub $x" is actually interpreted as "$x->sub"). It currently does not warn when the object is enclosed between braces (like "meth { $obj } @args") or for core functions ("print" or "say"). This may change in the future, or may be added as optional features that would be enabled by passing options to "unimport". This module is not a source filter. METHODS "unimport @opts" 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. "import" Magically called at each "use indirect". Turns the module off. DEPENDENCIES perl 5.9.4. XSLoader (standard since perl 5.006). 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 token before the end (as in "meth $obj;" or "meth $obj 1").
