Oh, OK, similar to what I proposed earlier. That it was rejected is not 
a surprise. Programming languages seem to hate special forms for basic 
constructs such as looping, even though they can express more directly 
exactly what the coder intended.

But this is what it says about it:

"Please reject the PEP. More variations along these lines won't make the
language more elegant or easier to learn. They'd just save a few hasty
folks some typing while making others who have to read/maintain their 
code wonder what it means."

Exactly the same could be said of pretty much any of the advanced 
features that /have/ been added.
