Or the much requested 3to2 using the same tools.


I didn't know there was such a request. I thought it was only a PyPy April fool.
Some of the people who need to support both late 2.x and 3.x would prefer to write 3.x code and backport. The OP of a current python-list thread asked whether there was any way to write something like 

        @alias('__nonzero__')
        def __bool__(self): return True
(in preference to explicit 'if version....') and have .__bool__ be either replaced or aliased as .__nonzero__ for a 2.x version. Answer: No. Use 3to2 if/when available. 

This has been the answer in other threads as well.

I believe my own 3.0 code will mainly also need
print() to print statement
except e as a to 2.x version
class C() to class C(object)

An easily doable project would be both used and appreciated.
