in thread Cancel/no-op a require

Ah, so this particular sentence in perlfunc is the one that gets me confused: The subroutine should return either nothing or else a list of up to three values in the following order.

So instead of returning (undef, sub{...}) I should've just returned (sub {...}).

Thanks, Toby.

    Also the innards of the function are kinda odd. You need to assign lines to $_ rather than returning them. I can understand why they did it that way, but it's pretty strange.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
