- Subject: Re: Protect global table from any changes

Luau (Roblox’s custom Lua implementation) does it right by allowing flagging any table as read only. Trying to modify a read only table raises an error.
Since the branches needed to implement this inside the VM are very coherent, the performance overhead is pretty small. I think it would make sense for Lua to support this as well.
