Again I don't see what you are attempting. Python has no concept of "passing
arguments to a property", there's no reason why this should work, and I don't
know what it would mean if it did?
Why is it that you cannot simply implement __getitem__?
If you want "x.y[z]", do
cdef class YAttr:
def __getitem__(self, z): ...
cdef class XObject:
cdef public YAttr data

Incidentally, this doesn't work:
