OK, so the question would be: how much does this slow down regular
method dispatch like s:sub(i,i)?

I'm ambivalent about 'global subclassing' because it can be very cool
for small programs but doesn't play nice with other people's code
(especially if they have decided to override the string metatable for
their own purposes ;))
