... the while-loop EXPR [is] re-evaluated after each iteration...

It is, but I was trying to make a (perhaps rather trivial) point with regard to continued execution of the loop body (which I've tried to clarify in the original reply) as exemplified below.

>perl -wMstrict -le "my @ra = (9, 8, 7); ;; while (@ra) { print 0+@ra, ' in @ra'; shift @ra; print 0+@ra, ' in @ra'; shift @ra; print 0+@ra, ' in @ra'; shift @ra; print 0+@ra, ' in @ra'; shift @ra; print 0+@ra, ' in @ra'; shift @ra; print 0+@ra, ' in @ra'; } " 3 in @ra 2 in @ra 1 in @ra 0 in @ra 0 in @ra 0 in @ra
