Detailed Description

DVM Context.

A context is the part of a token tag. Contexts differentiate between various instances of a single part of the program.

For instance, when calling a function, DVM will create a new context shared by all the arguments to this function. Upon returning, the context will be used to find the destination of the function results.

Internally, a context is a wrapper around a unique integer.
