Re: Warning for "unused sub declarations"?

How could Perl know this in the face of AUTOLOAD, run-time module loading, and symbol table manipulation?

The best I can see it doing is trying to resolve subroutine calls as they happen and throwing errors if it can't find them.

(I think your code has a bareword problem that makes it give an ambiguous error message, but that's just a guess looking at the snippet and not its context.)

How could Perl know this in the face of AUTOLOAD, run-time module loading, and symbol table manipulation? It wouldn't be foolproof, but could the warning be somewhat like the "Name %s used only once" warnings with package variables? Example included for those who don't know what I'm talking about: `$ perl -wle '$foo = 1; print 5' Name "main::foo" used only once: possible typo at -e line 1. 5` [download]	[reply] [d/l]

Not to mention even `$obj->$method( )` or `$methref = $obj->can( "kwyjibo" )`.	[reply] [d/l] [select]
