The one good thing about Basic: you write `NEXT I` at the end of 
a loop with control variable `I`.  In Lua, if the loop is at all 
long, I write as a habit

    for k,v in pairs(t)
        -- (half a page of code)
        end -- k,v

On the other hand, if a loop and a conditional, or nested loops, 
have the same body, I write as a habit

    for i=1,n  if x[i]~=0
        -- (body)
        end end

Would this last usage be improved by `end2`?  Basically, I agree
with Steve: no.
