| Subject: | Does not accept Math::BigInt objects as input |
It would be convenient if Math::GMPz accepted Math::BigInt objects in new(), ideally including overloads. Math::BigInt is a standard Perl method for big integers, so is quite common. Math::GMPz is *much* faster both in operations but also overhead, so is nice to use when doing lots of operations.
I suspect just stringifying the input is enough, so it works regardless of back end. But if you find a good non-brittle way to dig into the backend and optimize the Math::BigInt::GMP case, that would be awesome.
$ perl -E 'use Math::GMPz; use Math::BigInt; my $n = Math::BigInt->new(10); my $m = Math::GMPz->new($n); say "$n $m";'

For comparison:
$ perl -E 'use Math::GMP; use Math::BigInt; my $n = Math::BigInt->new(10); my $m = Math::GMP->new($n); say "$n $m";'
