Remember the two rules of optimising your code:

1. Do not optimise your code.
2. (for experts only) Do not optimise your code yet.

You may find the metatable trick is plenty fast enough --- if you really are
doing time-critical processing, then you won't be able to tell for sure until
you measure it. Intuition is frequently wrong.

That said, you may find this idiom useful:

local string_gsub = string.gsub

...

a = string_gsub(s, p, r)

It saves two table lookups per call.

Still not working, I'm afraid.
