Consider dyncall implementation

may be preferred in some environments over libffi (?). it's a question.

If i remember correctly, Rakudo Perl 6's MoarVM is using it.
https://github.com/MoarVM/dyncall/tree/1dabd7c2fd438920502c85eaf9ca4212d722c4b5.

What are the technical merits of using dyncall vs libffi? performance or more supported platforms?

Also found this interesting link on FFI overhead in various languages.

I discovered dyncall from looking at the Perl 6 source. You can correct me if I am wrong, but I think both dyncall and libffi are supported, the original was dyncall and libffi was added for platforms that didn't support dyncall.

From my perspective having multiple implementations would insulate FFI::Platypus from being dependent on a single implementation. libffi is pretty good but they haven't had a release in years. The most recent release doesn't build correctly on windows (Alien::FFI has some logic to use the previous release on windows). They are threatening to do another release 🤞 though :)

It looks like libffi's latest release is 3.4.2 from Jun 2021, if that makes a difference.

Yes some of the commentary here is out of date, but I still think there is some potentially utility on having an alternate implementation.
