Comment (by SimonKing):
Both patches are updated, I guess we can now focus on the remaining issue
with properties.
I asked whether it'd make sense to cythonize lazy_attribute. I think it
does not, because we want to override `__name__` of an instance which
won't work in a cdef class.
In addition, it would be bad for speed if the property needed to first
look up a name and then try to find this name as a key of
`__cached_methods`. Would it be acceptable to have two specialised non-
data descriptors with fixed names `_domain` and `_codomain`, rather than
implementing a general non-data descriptor that can take any name?
