Comment (by jdemeyer):
This patch abuses `assert` and `AssertionError`. `assert` should not be
used for control flow. An `assert` checks something which should always be
true, a failed assertion is always a bug in the program.
For example:
{{{
sage: f.skew_by([1])
Traceback (most recent call last):
...
AssertionError: x needs to be a symmetric function
}}}
This is a simple user mistake, for which `assert` is not right.
I think this must be fixed.
