G'day achs,

You are missing a closing </code> tag which makes your post unreadable. Please fix this (see "How do I change/delete my post?" if you don't know how to do that). Please also fix your title: remove the umlaut and match quotes (see my title).

I see you've used quotemeta in various places. You may be suffering from this problem: 

$ perl -wE 'my $k = q{a.b}; my %h = ($k, 1); say exists $h{$k} ? 1 : 0
+;'
1
$ perl -wE 'my $k = q{a.b}; my %h = ($k, 1); say exists $h{quotemeta $
+k} ? 1 : 0;'
0

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
