Not fully, I'll admit.  I found that the following are invalid in a .pxd:

cdef class Cls:

   def method(a)

   cpdef method(a)

I later found that just using @staticmethod\n def method(a) in a .py 
file does work (I'm using pure mode).  That means that cython code in 
other modules is doing a PyObject_GetAttr to get the method and then 
calling the returned object (admittedly I'm not far enough along to 
profile to see if this is a real problem or not).

I think I'm really asking about cpdef staticmethods.
