You need to be very careful using this idiom, especially
if you're hoing to embed loops. It's very easy to mix up
which $_ belongs to which loop and create
some horrendous problems.
In general I find it's better to name (and declare) the iteration variables unless it's really going to be a short loop (in which case I tend to use the statement modifier expr for (@array) in any case)
