I think arbitrary next-item functions are best.

If this is the example loop:

#declare Count=0;
#while (Count<MaxItems)
  blah(Count)
  #declare Count=Count+1;
#end // while (Count<MaxItems)

This form would be perfectly familiar to all the C users out there:

#for (Count=0; Count<MaxItems; Count=Count+1)
  blah(Count)
#end // for (Count=0; Count<MaxItems; Count=Count+1)

Other languages are different, of course, but C seems to be "common ground".

I don't think assignments, comparisons, or statements can be passed as macro
arguments, but if they could be, something like this would almost work:

#macro for(init, check, inc, body)
#declare init
#while (check)
  body
  #declare inc
#end // macro for

That's what I've seen in other source files -- wish I had more experience, but
I'm still the new guy. :-P
