Alas, but no Lua mechanism exists to perform some action at scope end;
will have to explicitly restore string state.  If we had deterministic
finalizers[1]  then it would be straightforward.

Another idea that was floating around is that the metatable of
strings, etc could be tied to the current environment[2].  Then a
person could happily monkey-patch within their modules without any
other code being bothered.

[1] yes, there's a patch out there
[2] in 5.2 terms, whatever _ENV is pointing to...
