... File handles can use oop syntax;Strings can use oop syntax (only thing you don't call a library function to create that has a metatable); So why can't threads? They're like file handles, as in you call a library function to create them. This would just increase consistency a bit. (another option would be to make it so file handles don't have a metatable and you have to call io.write(fd, ...) and such instead)
(I can't think of anything else that would feel "better" with metatables... adding metatables to numbers (with __index being `math`) would be just weird: n:tointeger(), n:pow(0.5), etc (mostly because they're, y'know, _math_ functions. if we had a `number` library then /maybe/ I'd be ok with it.))
