Here's another possible use of mpz pointers:
And another one, I just stumbled upon: Passing mpz_t to varargs
functions,
mpz_srcptr n = va_arg(args, mpz_srcptr);
(I just edited that line to use mpz_srcptr. When I wrote the previous
version 10 years

Hmm...can one use Newton for any a^(-1) mod b (when that exists)? (I
listed gcdext for the sake of inverses, and omitted gcd.)
I think Newton analogues exist only when b is a power, not in general.
And the most important case is prime b.
I am not
