Re: Re: How do I pass a block like map/grep/sort/etc?

Sweet, I didn't know about '&', I couldn't find it when I was looking for prototypes earlier. How do these functions get away with being unprototyped though (i.e. print prototype "grep"; prints nothing).

Quoth `perldoc -f prototype`: If the builtin is not overridable (such as "qw//") or its arguments cannot be expressed by a prototype (such as "system") returns "undef" because the builtin does not really behave like a Perl function.	[reply]
