I don't think the design reason would be "we don't want ppl to sandbox 
the string metatable so we make it impossible for getmetatable to 
natively call __metatable if it's a function and also make it impossible 
to override that behaviour properly without the debug lib"...

So any way to sandbox the string metatable without the debug lib?
