@hardlyardi hardlyardi commented Dec 26, 2025

currently the RFC specifies this behavior:

the __index metamethod will only be invoked if the indexer is not found within the current scope

this will be changed to:

the type should reflect the result of the expression (tableValue & ~nil) | (__indexValue) where ~ is the negation type symbol.

this better represents the actual runtime behavior for metatables
