My gut feeling is that modules are not the best way of bringing this
to Emacs (and doing this via Rust on top of that makes even less sense
to me), which is why I suggested to come up with a design first.

They compile to C, and I'm quite sure that it shouldn't be too hard to
allow a language grammar to be written in some other scripting
language.  But I think these are secondary considerations at this
stage.
