Thanks for the quick input! However, this is one of the very rare points I
intently did that way, because of the difference in meaning from "==" to "is"
(see
http://stackoverflow.com/questions/1504717/why-does-comparing-strings-in-python-using-either-or-is-sometimes-produce).
But I'm curious, how would one then properly compare the content of two strings?
Checking both types first?
