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.
