It appears the only solutions are (apart from relying on the user to
supply needed precision):
A) restrict the range of parameters where ticket is applied
B) do not simplify; just fix the evaluation problem
C) declare the problem to be in `n()`
I mean really, `n()` makes bold claims:
{{{
Returns a numerical approximation of an object "x" with at least
"prec" bits (or decimal "digits") of precision.
}}}
but won't deliver when `x` is a polynomial?
