I am wondering if there is some way to improve the
imperative loop operations slightly, to give programmers
better control over areas of their code that have to
run fast... The following would be nice:

1. step values for for loops. Example:

   for i = 0 to 9 by 2 do
   Printf.printf "%d " i
   done

   0 2 4 6 8

2. break statements ("exit loop", or whatever). I realize that break can be
   simulated by using reference variables to control while loops
   and setting the variable such that the toplevel test will fail,
   but this is not an appealing way to program. I also realize that
   break can be simulated by exception throwing, but I've noticed this
   is slow compared to the first simulation method.
