Comment (by ppurka):
Replying to [comment:12 dkrenn]:
> Hmm...IMHO this is not ideal. It should be the other way around, i.e.,
the general {{{factorial}}}-function should check if the element has
{{{.factorial}}} and executes it. Only if not, it comes up with solution
on its own. (I have not checked the current implementations; its just came
in my mind by thinking about it).
I was thinking about that too, but it seems that the generic factorial
function is in cython -- the one in `sage/functions/other.py` is just a
shell function/class to use `ZZ.factorial()` if it is an integer.
