before (as opposed to `def` or `cdef` or `class`).
I also found out about it while looking through the Sage library code for
a way to make `numpy` work when I define `__getitem__()`:
http://docs.cython.org/src/userguide/extension_types.html#properties
The function defined by `__get__()` is run when you access that property.
This makes the syntax look much cleaner. You don't need to put `()` at the
end any more, compared to the syntax needed for `.operands()`.

No, it should be independent. Though I admit that there are a bunch of
symbolics patches before this on my queue.
