Comment (by SimonKing):
There is one nasty detail with singular_function. If one sets `ring =
singular_function('ring')` and then uses the singular_function to create a
ring, then its reference counter is ''not'' incremented, even though the
following function is called in this case:
{{{
cdef inline RingWrap new_RingWrap(ring* r):
cdef RingWrap ring_wrap_result = PY_NEW(RingWrap)
ring_wrap_result._ring = r
ring_wrap_result._ring.ref += 1
return ring_wrap_result
}}}
I do not understand it, yet. But anyway, that's the problem I am currently
dealing with.
