lib_getenum works functionally identically to how it worked before I made any changes.
The difference is now getEnum contains the main comparison portion.
The constants userdata uses an anonymous metatable.
Lua people:
A new userdata named constants now exists for you to get the value of a constant, or check if it exists. This is helpful for seeing if a value in _G is a constant or not.
This read-only userdata expects table accesses with strings as keys. Failed accesses will return nil with no errors.
Example: print(constants["FRACUNIT"]) -- 65536
userdata and function type variables are excluded from constants, so A_* and super aren't considered constants.
Attached is a Lua script you can use to test the code. constantTable.lua
