I'm not silly enough to think I've found a bug, I must be doing something I simply don't understand.

Using perl 5.8.4.

I typod and missing the closing curly brace in a numeric range in a regular expression. It did not error out, only missed the matches I expected in my test.

Would this be considered correct behaviour?

Sample code: 
#!/usr/bin/perl -w

use strict;

while (<DATA>){
    chomp;
    #
    # Incorrect REGEXP - missing closing curly   !
    #                                            V
    if (/(&[A-Z0-9\.]+:LU)((\d{1,2};\d{1,2})|(\d{1,2)|LD|LC)?/){
        my $lookup = $1;
        my $type = $2;
        $type ||= '';
        print "1. Lookup: [$lookup]:[$type]:[$_]\n";
    }
    #
    # Correct REGEXP - notmissing closing curly  !
    #                                            V
    if (/(&[A-Z0-9\.]+:LU)((\d{1,2};\d{1,2})|(\d{1,2})|LD|LC)?/){
        my $lookup = $1;
        my $type = $2;
        $type ||= '';
        print "2. Lookup: [$lookup]:[$type]:[$_]\n";
    }
}
