Comment (by vdelecroix):
I do not completely understand the end your comment. The code I have
written was precisely to avoid any conversion. You can have a look at
#19822: there is no type conversion at all (except some `NTL -> FLINT`
integer conversions).
I agree that we have two places for the implementation of
`IntegerPolynomial.__call__(ArbType)`:
1. in integer polynomials `__call__` (as in #19822)
2. in arb `_evaluate_polynomial`
I have no strong opinion about what is best. Though I provided a shurtcut
`p._eval_mpfr_(x)` which is useful and avoid type checking. This is does
not discard using 1. or 2. for the generic call to `__call__`.
