No, it isn't.  You add a decorator, a 'from_' class, and a 'return_' 
function, and there you go.  (See my previous code sketches here in 
early PEP 380 discussions.)

Python frameworks have been doing variations of the same thing (with 
varying features and APIs) for at least 7 years now -- even on Python 
versions that lack decorators or the ability to return values from 
yield statements.

So the main benefit of a PEP for this functionality would be 
providing a common implementation/API - and that could be initially 
done in the stdlib, without any added syntax support.
