When to use state design pattern

Any LuaValue can be used as a stand-in for Varargs, for both calls and return values. When doing so, nargs() will return 1 and arg1() or arg(1) will return this. 1 argument or 1 return value. Varargs can also be derived from other varargs by appending to the front with a call To return a variable, simply type out the keyword "return" followed by the values, separated by commas, that you want to return. You can return multiple values that can be either literals or variables. For the caller to get all the variables the function returns, they also so a variable nameholder list seperated by commas. Again, only the value is passed so the values returned take on the variable name the function caller gives it.

Preface. I wrote this because writing out something is the only way I can get to understand it for myself. It's aimed at readers who think they know the Lua 5.2 Reference Manual (LRM5.2) pretty well, have a little experience with the machine instructions of at least one machine (Knuth's MIX will do) and would like to do some tinkering with code for the Lua 5.2 Virtual Machine (VM5.2). In this final tutorial on Lua functions we learn about returning values from a function.
