Comment (by nbruin):
Why don't you do something along the lines of:
{{{
cdef cparent get_cparent(parent) except? NULL:
if parent is None:
return NULL
cdef ntl_ZZ_pEContext_class c
try:
c = parent._modulus
except KeyError:
c = <some vaguely appropriate proxy value>
return &(c.x)
}}}
This should really only be happening upon deletion anyway and I I'd be
surprised if having the correct `_modulus` is very important at that
point. It's a dirty hack but alternatives probably mean a full
reimplementation of these polynomial rings.
