This module provides a number of basic mathematical operations.]] local yesno, getArgs-- lazily initialized local p = {}-- Holds functions to be returned from #invoke, and functions to make available to other Lua modules. local wrap = {}-- Holds wrapper functions that process arguments from #invoke. These act as intemediary between functions ...

Function names are often of the form p.myFunctionName, where p is the table from the return p at the bottom of your program. The reason for this is that you can only access functions that are entries in this table from the original #invoke statement. Functions for local use within the program can have any name.
Marshalling data between C and Lua functions is also done using the stack. To call a Lua function, arguments are pushed onto the stack, and then the lua_call is used to call the actual function. When writing a C function to be directly called from Lua, the arguments are read from the stack. Here is an example of calling a Lua function from C:
The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
Non-local variables are the primary reason it is difficult to support nested, anonymous, higher-order and thereby first-class functions in a programming language. If the nested function or functions are (mutually) recursive, it becomes hard for the compiler to know exactly where on the call stack the non-local variable was allocated, as the frame pointer only points to the local variable of ...
The functions of the Module:SimpleDebug can be used for cases such as those mentioned above or for more complex cases: When variables or the returned value (or values) by a function are local. To see if the flow of the program goes through a point (to which you will label).
