Such a bit of sugar would also be useful with pcall.

Actually, there's no reason to use rawget/rawset, instead just:

   function s.__newindex(t,i,val) t.store[i] = val end

and so forth. Then t.store could be userdata.

Now, it would be cool if table.concat was intelligent enough to
understand such proxy arrays (i.e. use the overloadable ipairs, and
use tostring where applicable) without much performance cost.
