I believe that might have happened already for the loop var *within* a list 
comprehension, and maybe within a generator expression (easy to test).  As 
I remember, the idea has been explicitly rejected for the loop var in for 
statements, which will remain compatible with equivalent while loops with 
explicitly assigned vars.
