Maybe 

   do
   until (CONDITION)

I would probably find a way to use any form of this, so I don't
really care one way or another.  If I were going to implement
it, I would use the form easiest to parse (which may not be 
using `while').  

FWIW, in a current code I have a couple of do whiles  nested in 
a for loop.  So it can be very handy once in a while.

Thanks,
