Comment (by jdemeyer):
Why do we have `__call__` and `_eval_` given they do essentially the same
thing? Please keep in mind [comment:69] also in the `_eval_()` function (I
really don't understand why it needs to be so complicated).
This is also still broken:
{{{
sage: parent(chebyshev_T(4, RIF(5)))
Real Field with 53 bits of precision
}}}
Please fix all issues that I mentioned '''and turn them into doctests'''.
