This is wrong. Loop variables are not exapnded on each loop iteration.
Each loop iteration effectively creates a new variable. The rest of his
confusion comes from two simple facts:
(1) += is lazy in bmake. This is different from FreeBSD, where it forces
expansion.
(2) The evaluation of j is lazy as well. That's why he sees the last
loop iteration.

Therefore I don't agree with the content and it is actually making
things a lot more complicated than necessary.
