I had a similar problem for the PyPy project. In order
to overcome the problem of always having to call
conversion functions, I wrote a class that tries
to promote its restricted type through expressions.
So if you start a variable by
x = r_int(42)
and perform any integer operations on it, the result
will stay in the same domain.
Feel free to use the attached code as you like.
