Would you settle for just the x++ ?
Something tells me the -- is already spoken for.

If I recall correctly, that would be impossible with Euphoria, which makes 
a copy of the loop variables before beginning, so any change would be 
disregarded.  Let's see:

atom x, y 

x = 1
y = 10
for i = x to y do
    x -=1
    ? i
 end for    

Yep, counts from 1 to 10.
