   Sorry, I should have followed that last bit with a smiley :-)

   I can see no reason why it is a bad idea (from a programming standpoint).
   And I can come up with a reason why it is a good idea (side effects):

	 while (min < *ptr++ < max) ...

   I can see no way to do this sort of thing as cleanly with ``< && <''.
   I compiler writer might have other opinions though!
