It's generally a bother writing wrappers around tables, because as
soon as you introduce some convenient helper methods, they will
collide with some arbitrary key that the user wants to store. pl.Map
suffers from this problem, which is why pl.Set has no methods. There
are fixes but they are expensive.

But, back to topic: currently, the rules are simple. Adding arbitrary
extra rules makes it harder to explain and use the language.
