The core features of primer are general-purpose lua binding facilities.

They do not rely on lua eris, and can be useful in an application which only uses vanilla lua 5.3 or 5.2. They also don't particularly rely on much of the standard library.

These features serve such purposes as:

transferring C++ objects to and from the lua stack
constructing C++ objects as lua userdata
transforming C++ functions into functions that can be called from lua scripts
constructing C++ objects that represent references to pure lua values in a VM, such as functions and coroutines.
