This would be useful if we had a good C++ FFI. Without it, you'd probably end up writing shims anyway.

It's something to keep in mind though, so it doesn't hurt to let this open.

I had a brief look at using SWIG with the experimental C back-end from swig/swig#2086, but ran into a few problems. Documenting those here:
- SWIG doesn't handle
_MTL_INLINE(but we cansedthat away) - callbacks are blocks, not ordinary function pointers: https://en.wikipedia.org/wiki/Blocks_(C_language_extension). Maybe we can treat those without captures like ordinary function pointers (i.e. remove the
(^)), but not all (e.g.newBuffer(const void* pointer, NS::UInteger length, MTL::ResourceOptions options, void (^deallocator)(void*, NS::UInteger)))
