If anything, the trend is *away* from C-coding modules - certainly for
first implementation (as with sets).  There is some thought that some
things should be lifted from C back to Python.  PyPy is just an
extreme example.  I think C should be reserved for inner-loop stuff.
I don't see that currying qualifies.

In anycase, distribution as a third-party module is much easier as
Python than C code.
