(see also Re^3: Strange aliasing(?) when modifying variable in range operator)

I think it's the right side of for which is a statement in it self and does optimization (foreach has lot's of magic, it's also aliasing)

BUT ... (wow oO ???)

 DB<3> $i=0; say for do{$i},$i++
0
0

apparently different levels of optimizations are exposed here when the debugger does an eval on the entered line.
