Every time I see posts formatted like this:

sub foo
{
foreach my $thing (@_)
{
# do something
}
    }
    print "Hello\n";
print "something else\n";

I take for granted that there's no way the code is going to compile. Not that formatting has anything to do with compiling, but lack of formatting almost guarantees the sort of sloppy attention to detail that will assure compile-readyness is not a foregone conclusion.
