Re^2: array value generation for sections

I am just wondering why you use return return. If I would be at home, with Perl installed on the computer, I would have tested. My guess is that is has something to do with references.
But I'm at school. No Perl here. So would you be so kind to explain?

I think it is just a typo. It does compile OK with "return return" (which surprised me, actually) but it works just as well with just the one `return`. Update: If you consider that `return EXPR` is just an expression with the value `EXPR`, but with the added side effect of returning control to the caller of the sub, then it makes sense that you can put `return` as many times as you like. Including (in this case, since it's the last line of the sub) zero times. s^^unp(;75N=&9I<V@`ack(u,^;s\|\(.+\`\|"$`$'\"$&\"\)"\|ee;/m.+h/&&print$&;	[reply] [d/l] [select]
