not even in the for loop?
Oops - good spot - apologies to OP.
some languages make it UB to acces the for loop variable
outside the loop (I think- Pascal, Alogol-60 and Ada)
but I think it is guaranteed to point one past the end
of the array after exiting from a "normal" for-loop.
(I can't be arsed to define the exit value in Standarese).
