What about this code:

    cdef int i
    cdef float f
    cdef object o
    o = i = f = 1

I think the current way to split the assignments and handle them
separately isn't bad at all. This gives us the pretty code for my example.

That's most likely something that the C compiler would do anyway, but that
aside, there already is some special handling code for True, False and
None that should be easy to adopt here. I think doing the same thing in
the case of cascading assignments is the right fix for now.
