Yep, it seems to do (though it's not built-in OR standard). Untested: `use Devel::Caller 'caller_cv'; sub foo { my $selfref = caller_cv(0); # ... }` [download]	[reply] [d/l]

Oooh, that uses PadWalker. Well, that should work, but I wouldn't go as far as calling that "generic". "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

Joost, Chuckle - I will share a snippet of the CB conversation I had along those lines: Corion Seems like calin wants something like caller(-1) ... I wonder more about caller(-2) though - now that would be a feature of Perl to make other languages envious :-) Limbic~Region was just reading that Corion Corion Hmm - no, caller(0) does almost everything calin wants, except that it only returns a name not a reference ... But why should caller be restricted to non-negative numbers ? :-)))) Limbic~Region shrug - I am betting someone comes up with a B:: solution or something though the question looked to be asking for something generic Limbic~Region does Devel::Caller fill in the missing code ref? Corion Limbic~Region++ indeed! Zaxo suspects diotalevi will come up with something clever and wicked Note: Quotes used with permission Cheers - L~R	[reply]
