Ahh, yes. I see what you mean. Explains why it didn't appear the first
time I posted (until later..).
Sorry for bother and thanks for the advice.

The functions are ported from a java class static methods. I was trying
to be "pythonic" - since my 100 functions don't share state, I thought
they should be packaged as a module rather than as a class of bunch of
effectively static methods.

Genius! Embarrassingly, I hadn't realised that __getattr__() is called
when a method is invoked, thus making the method name (attribute name)
so easily available as a string. I was therefore thinking in terms of
gnarly introspection/reflection things. This is much better.
Thanks very much
