Re: [ANN] CLX - Ahead-of-Time Lua 5.5 Compiler

CLX coroutines are stackful.

Internally they use ucontext (POSIX) or Windows Fibers (Windows), so 
yielding is implemented as a context switch between execution contexts 
rather than via longjmp.

This means local state and call frames remain intact across yields.

For native C++ modules, yielding follows the same coroutine semantics as 
Lua: execution can be suspended and resumed without manually preserving 
state.
