__call and co() makes it look like a function call, which may be kinda
confusing. On the other hand OOP syntax co:resume() is more Lua-like, as
strings have it too. You also cannot index functions.

 Yes you can.
	function foo(x)
	 return 3 * x + 5
	end
	mt =
	{
	 __index = function(obj,idx)
	 local d = string.dump(obj)
	 return d:sub(idx,idx)
	 end
	}
	
	debug.setmetatable(foo,mt)

Try it without debug.

	lua_getglobal(L,"foo");
	lua_getglobal(L,"mt");
	lua_setmetatable(L,-2);

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.))
