in reply to Re^2: Count and List Items in a List
in thread Count and List Items in a List

This is perl, v5.8.6 built for i686-linux Rate foreach map foreach 47168/s -- -2% map 48260/s 2% --

That said, I always prefer code that does what it says and says what it does. To me, for/foreach evaluates code foreach element in a list, while map maps (or transforms) one list into another. If you want to iterate over a list, use for or foreach. If you want to transform from one list to another, use map.
