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.
