Yes, given that there is no index operator for strings it seems odd
that we don't get an error. The reason is that strings have a
metatable with __index pointing to the string table; looking up  on
s leads to string which gives the nil as you've noticed.
If you're prepared to modify the metatable of all strings, then you
can define a in this case to be a:sub(3,3)
