Hi, if I have a function that writes something to STDOUT or STDERR, for example: 
use strict;

sub foo(){
   # this could be a loop that takes some time to finish.
   print STDERR "Something to worry about\n";
}

How do I capture this in the main script? i.e., in the main script, I'll call foo(), wait for it to exist, and capture everything it printed to STDERR, I'll then process that string.
