Re: elements not reversing inside a map

reverse in a list context is a list reverse. If you want a string reverse, you have to have a scalar context. Try adding "scalar" in front of your first "reverse".

Ok, I had overlooked that map evaluated $_ in a list context. My question below stil stands, however. Why does (reverse $_)\|\|"" work?	[reply]

Because it puts it into scalar context? -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

Ok, but why? Shouldn't the short-circuit operator take effect then? From perlop: Scalar or list context propagates down to the right operand if it is evaluated. But that's "if" it is evaluated... which it doesn't seem like it would be.	[reply]
