When I tried your code like so:
open my $fh, '<', $file or die qq(Unable to open $file: $! );
<$fh> x {/^\s*#/ or print};
close $fh or die qq(Unable to close $file: $! );
I get these errors:
Useless use of repeat (x) in void context at ./test line 48.
Use of uninitialized value in pattern match (m//) at ./test line 48,
<$fh> line 1.
Use of uninitialized value in print at ./test line 48, <$fh> line 1.
Odd number of elements in anonymous hash at ./test line 48, <$fh> line 1.
Out of memory!
I'm using Perl 5.8.8.
How can that line be used?
Thanks,
Mike
