Re: __type for better typing

[askok@...]

I second something like this would be useful.

My enum approach uses a __typeof() function within the 
metatable, which can be a constant string, too.   A well 
thought out system could be useful for tables, userdata 
and enums all of them.

Basically, I'd see this as a "subtype", and make type() 
return two values, instead of the one it now returns. 
This way, compatibility hick-ups could be smaller, too?
