The for is acting on @_ which in perl is 'the array i'm currently looking at' and in this scope is the list you passed to strip. ugly code though.

for the other use Proc::Fork; is probably of interest

see http://search.cpan.org/~aristotle/Proc-Fork-0.71/lib/Proc/Fork.pm
run_fork -creates a fork for the block
child - declares the block to run with a child
