Hi all - I'm trying to identify comments in code (so that ultimately I'll strip them out). I've tried using Regexp::Common::comment, but it appears to detect comments in strings when they should really be ignored. Am I using it wrong, or is it a limitation of the module? 
use strict;
use Regexp::Common qw /comment/;

my @tests = (
    {
        language => 'PL/SQL',
        description => 'PL/SQL Comment in String',
        code => q{
            declare
                 j varchar2(2);
            begin
                j := '--';
            end;
        }
    },    
    {
        language => 'PL/SQL',
        description => 'PL/SQL no comment',
        code => q{
            declare
                 j varchar2(2);
            begin
                j := 'xx';
            end;
        }
    },
    {
        language => 'SQL',
        description => 'SQL Comment in String',
        code => q{
            select '--'
            from dual;
        }
    },    
    {
        language => 'SQL',
        description => 'SQL no comment',
        code => q{
            select 'xx'
            from dual;
        }
    },        
    {
        language => 'Perl',
        description => 'Perl Comment in String',
        code => q{
            my $j = '#';
        }
    },    
    {
        language => 'Perl',
        description => 'Perl no comment',
        code => q{
            my $j = 'xx';
        }
    }
);

foreach my $test (@tests) {
    print $test->{description}."\n";
    if ($RE{comment}{$test->{language}}->matches($test->{code})) {
        print "\tcontains comment\n";
    } else {
        print "\tno comment\n";
    }
}
