Ist zwar syntaktisch korrekt, aber bei ")as" drehen sich mir die 
Zehnnägel hoch. Bitte mach ein Leerzeichen hinter die schließende Klammer.

Sollte besser True (bei Erfolg) und False (bei Fehler) zurückgeben.

Hint: Die öffnende Klammer hinter "copy_and_compare" und Du kannst Dir 
den Backslash sparen.
