And the point would be, that you can get Lua to do just about anything
you like, at some performance cost. The sugar s[i] for accessing the
'character' at the ith index now slows down all string method lookups.
Personally I feel it's best to keep using s:sub(i,i) because then
you're always aware of the cost of creating a substring.
