Would calling it "c_foo" make you feel any better?

I'm not sure what could be done to make this any easier,
short of having some magic by which the same name refers
to the C attribute in Pyrex and the Python property in
Python. But you need to be able to refer to the property
in Pyrex as well, so I can't see how that would work.

Cython has a mechanism for making C methods callable from
Python as well as Pyrex, but last I heard, the implementation
is incorrect in the presence of overriding+inheritance, and
the Cython people are unwilling to pay the performance cost
required to make it work properly.

Some version of this may appear in Pyrex eventually, when
I figure out how to implement it correctly. In the meantime,
I'm using "c_" prefixes to keep my Python and C methods
sorted out.
