Not at this point apparently: category_object.pyx, line 479:
def base_ring(self): # This should be in a category or elsewhere, but not
here
return self._base
def base(self):
return self._base
Maybe making them such would solve Simon's problem? And actually
accelerate things, since Cython could optimize (inline?) their call in
the coercion/arithmetic code.

Another trick to try would be add in Modules.ParentMethods:
def __init_extra__(self):
self.basis_ring = self.base_ring
therefore adding a short path for base_ring in all parents in Modules.
This should be rather safe (I don't expect the base_ring method to
change over time).
