Even better, given people proper FFI so they can import and use any of the tens

or hundreds of quality math libraries available.

That would also help to keep C core smaller, and relieve the dependency on core

devs to add bindings to future libraries when users want or need them.

 

A third of Emacs C core could have easily been implemented by users if they had

proper FFI exposed to Lisp instead of C modules which very few people use.
