And now I’ve learned something new about reverse. Hooray for DWIM.
Huh.
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.
Why not just:
$reversed = scalar reverse $string;?Well, quite.
Although your call to
scalaris unnecessary.Why does reverse $string return the original string, but an assignment e.g. : $reversed = reverse $string store the reversed string in the lvalue?
As the title implies, read the documentation.
late joining the party. 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’.
