SOme of these 'dwimminess' features make me a bit uncomfortable. I feel that if c gives me 'fred' then maybe it's not very /useful/, but at least it's consistent with my simple user model of the language. When convenience measures like making that result be 'derf' are mixed into the language, then it seems to me kind of like encountering an irregular verb in a natural language: it may make life easier on this one occasion for somebody but the whole edifice gets just a bit more complicated ... adding to the meme that Perl is 'too hard'. late joining the party.

I don't think that's a sane behaviour for reverse in scalar context (only ever used it with a single argument in scalar context), but I'll be damned if I can come up with a better alternative. Huh.
