Comment:
The changes in attachment:trac_8606.patch look good to me and all the
doctests pass. I'm ready to give this a positive review, but I have a
minor comment first:
Shouldn't we also drop the try/except clause around `parent_c(n)(self)`?
The error message returned by the `except` is not very helpful and I can't
think of any test case to actually fall in that clause. Note that if the
conversion `parent_c(n)(self)` fails, we get a `TypeError` not an
`AttributeError`:
{{{
sage: 5^('a')
Traceback (most recent call last):
...
TypeError: unsupported operand type(s) for ** or pow(): 'str' and 'str'
}}}
