Comment (by mmezzarobba):
Replying to [ticket:17727 jdemeyer]:
> We copy a short-cut from `sage/symbolic/function.pxd` for
[https://docs.python.org/2/c-api/number.html numbers] not inheriting from
`Element` (in particular Python `int` and `float`): we assume that these
do not have a parent.
IMHO it would be nice to add a note to that effect in the docstring of
`s.s.element.parent`. (Not that I really think anyone assigns parents to
objects derived from built-in number types... but the concept is important
enough that subtle points in its definition should be documented.)
