Modifying signature of ctor in class

[Joseph L. Casale]

I have a class factory where I dynamically add a constructor to the class output.
The method is a closure and works just fine, however to accommodate the varied
input its signature is (*args, **kwargs).

While I modify the doc strings, the ctor sig is not optimal. Without building
this a string and using eval, is there anything that can be done about this?

Thanks,
