Runtime:setCheckGlobals()

Overview

Allows the usage of global variables to be flagged. Because Lua automatically assumes that any variable it doesn't recognize is a global variable, typos in variable names can lead to unexpected behavior. For example, accessing a variable that has never been set will yield a value of nil.

Essentially, the usage of global variables in Lua code should be avoided. Using this function to enable the check for global variables will flag all such instances so they can be fixed.
