> I mentioned above that {{{nfhyperellpadicfrobenius}}} is not currently
exposed. However, this function does appear in
{{{src/sage/libs/pari/paridecl.pxd}}}. Does something else need to be done
in order to make it visible as a method of a PARI object?
The methods of PARI objecgt are in `gen.pxd/pyx`.
You should add a method there calling the C function.
Then in the hyperelliptic curve class, something like
{{{
pari(H.polynomial()).frobenius()
}}}
could be called.
Maybe a better option is to add a method directly in Sage's hyperelliptic
curve over finite field class.
I'll have some free time in a few hours, I can have a look as well.
