Riddle Stack

The Riddle interpreter uses an stack for most values; every frame is set up as follows:

elements	notes
arguments	arguments passed to the function; first argument is the function itself; if there are less arguments than the function expects, it is padded with Null; if there are more arguments than the function expects, this section grows to accomodate them.
named	named variables local to the function; does not include variables imported from the parent scope, those are in the scope table.
volatile	parts of the stack used for temporary values; when a function is called, the argument list is built in this region, and so the next frame is built here.

Additionally, a function has access to three additional locations where data can exist:

The global table where every global variable (including all built-in values exported by the user) resides
The data table, where constants required for the code for that function reside, and that is tied to the function prototype
The scope table, where values bound to the function prototype to generate a function instance are.

Values located in different places are targeted by different functions:

region	instructions
global	`LOADG`, `STORG`
scope	`LOADS`, `STORS`
local	`LOADL`, `STORL`
volatile	`PUSH`, `POP`, others
