Overview

An Invocation is a binding of the interpreter, a function, and arguments for the function together to represent a Call.

In essence, an Invocation is the step between the Call node in the AST and the result of calling a function. Functor resolution happens before creating an Invocation, meaning they can be passed around without concern for lexical scoping or the like. However, the entire functor is carried with an Invocation; matching to a specific definition does not happen until the Invocation is invoked.
