huh, there's already a solution that doesn't use any modules in this thread.

But apply can be implemented using map pretty easily. 

print OUTFILE map  { my $s = $_; $s =~ s/\s*#.*/; $s }
              grep { !/^\s*#/ }
              <INFILE>;

You could even merge the map with the grep, but then it looks like spagetti.
