NAME subs::auto - Read barewords as subroutine names. VERSION Version 0.02 SYNOPSIS { use subs::auto; foo; # Compile to "foo()" instead of "'foo'" # or croaking on strict subs foo $x; # Compile to "foo($x)" instead of "$x->foo" foo 1; # Compile to "foo(1)" instead of croaking foo 1, 2; # Compile to "foo(1, 2)" instead of croaking foo(@a); # Still ok foo->meth; # "'foo'->meth" if you have use'd foo somewhere, # or "foo()->meth" otherwise print foo 'wut'; # print to the filehandle foo if it's actually one, # or "foo()->print('wut')" otherwise } # ... but function calls will fail at run-time if you don't # actually define foo somewhere foo; # BANG DESCRIPTION This pragma lexically enables the parsing of any bareword as a subroutine name, except those which corresponds to an entry in %INC (expected to be class names) or whose symbol table entry has a IO slot (expected to be filehandles). You can pass options to "import" as key / value pairs : * "in => $pkg" Specifies on which package the pragma should act. Defaults to the current package. EXPORT None. CAVEATS "*{'::foo'}{CODE}" will appear as defined in a scope where the pragma is enabled, "foo" is used as a bareword, but is never actually defined afterwards. This may or may not be considered as Doing The Right Thing. However, "*{'::foo'}{CODE}" will always return the right value if you fetch it outside the pragma's scope. Actually, you can make it return the right value even in the pragma's scope by reading "*{'::foo'}{CODE}" outside (or by actually defining "foo", which is ultimately why you use this pragma, right ?). You have to open global filehandles outside of the scope of this pragma if you want them not to be treated as function calls. Or just use lexical filehandles and default ones as you should be. DEPENDENCIES perl 5.10.0. Carp (standard since perl 5), Symbol (since 5.002). Variable::Magic with "uvar" magic enabled (this should be assured by the required perl version).
