What are these? How are they used? What are they useful for? I was mucking around with F3X's source and saw this.

fenv means function environment. setfenv is used to set function environments, getfenv is used for getting function environments.

A function environment are the global variables a function has. By default (when you don't set it) all function environments inherit from the top-level function's environment (environments are inherited from enclosing functions) which is the global environment.
