As a roblox developer it is currently hard to make sure that I have number indexes in table only once because there isn’t currently any warning (such as string indexes have) that can warn me that I am using multiple of same number indexes. The fact that the index will be overwritten if there are more than one of the same index is making it so important to add this feature.
If Roblox is able to address this issue It would speed up my workflow and I wouldn’t need to check my table indexes everytime I add one.
