Luau supports continuations in its C API (see pushcclosurek's lua_Continuation argument as one place where it's supported). It would be nice if this was exposed somehow in mlua both as Luau's APIs seem to be increasingly expecting callers to have support for these (especially things like yielding require by string)

In addition, continuations could be useful for implementing concurrency primitives more performantly etc (such as custom task schedulers)

I don't have plans to support continuations in near future for any Lua version. The current async API covers all needs, works great and is runtime-agnostic. async-friendly "require by string" does not require continuation functions either.

However, I'm happy to review a PR with reasonable support of continuation functions.

Ah alright, I'll think about opening a PR then if I find myself really needing it
