That's even an inaccurate description, so an expert in Perl (I've known a few) would just scratch his head. You cannot ever ever return a list in a scalar context. Ever. Never ever. You can return an array ref that *contains* a list of references, sure. Perhaps that's what you mean, as in: return [$ref1, $ref2, $ref3, $ref4]; # scalar return But to be sloppy about the terminology confuses me. For example, I can't tell from your description if you mean the list-value return is: return \%some_hash, $ref1, $ref2, $ref3, $ref4; # list return: N items Or, reverse engineering your sloppiness on the other description, you *MIGHT* mean: return \%some_hash, [$ref1, $ref2, $ref3, $ref4]; # list return: 2 items Perl5 does *no* implicit referencing/dereferencing (just like C). So yes, being precise with your language is necessary. -- Randal L.
