 In AutoHotkey v1, there were several global collections of names that were kept separate. There was a collection of command names, a collection of label names, a collection of function names, and a collection of variable names. AutoHotkey v2 has mostly merged these collections, folding them all into the //just// variable name collection. Label-based subroutines have been replaced in favor of functions. Commands have been replaced in favor of functions. And, critically, functions have been redesigned to all be stored //inside// global variables. In AutoHotkey v1, there were several global collections of names that were kept separate.
