in reply to Bare BLOCK vrs. grep BLOCK

Hi, may be I am asking a dumb question, but why do you have (&@) in sub mygrep (&@) ? Shouldn't it just be sub mygrep { your greplike function code}?

    In perlsub subroutine prototypes are discussed. They are seldom needed, but a grep-like subroutine is one of the examples, and is shown using &@ as a prototype. This means to expect a subroutine and then a list.
