Hi,
first of all, thanks for your help, Simen. I think, I even found a 
better solution, I assign the name to the class with

Object.const_set class_name, klass

So I can determine, whether the class exists with

Object const_defined? class_name

You are using exception handling (rescue) for a conditional branch, 
which I try to avoid whenever possible, to keep my code well structured.
