I assume you are C programmer and want to prepare the user environment in C?

In this case the typicaly quite easy way would be to use the
yield/resume functunality of C interface (see Roberto "Programming in
Lua" somewhere in the "very later chapters").

The API I would like is for chunks to be loaded and run with each chunk leaving a function (with a closure) on the stack. This returned function will then be called periodically and will update state values. I'm trying to avoid requiring user code to use a designated name and trying to minimize the boilerplate of registering or assigning the function.
