Details
As of the introduction of getfenv() into the API, setglobal() and getglobal() are somewhat superfluous. You can always do something along the lines of:
local _G = getfenv() local prevval = _G["MyVariable"] -- "getglobal()" _G["MyVariable"] = 1234 -- "setglobal()"
Function calls always cost some overhead, so if a large number of getglobal calls are being made, the getfenv table will be a faster route. Note that for few or infrequent calls the performance gain of this method is negligible.
