foreach s[index] do 
-- whatever 
end foreach --<-- when do we get rid of that redundancy? 

The redundancy is only in the eyes of the interpreter. It doesn't need it. But the end XXX serves another purpose. Source code is actually meant for people to read, not programs to read, and people are not as efficient at symbol processing, so we need a certain amount of redundancy to help us understand what we are reading.
