Anmerkung: Ich habe hier [ code ] und nicht [ perl ] genommen, weil letzteres buggy ist. Dort wird u.a. falsch eingerückt...
Außerdem sind die Farben so verstörend, dass ich den Code lieber s/w sehe...
Edit: Auch bei Code wird immer noch das erste Leerzeichen entfernt :(
Edit2: fehlende Leerzeichen von Hand ergänzt :-/\n\n
