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
How about simply: __nonzero__ = __bool__
I believe my own 3.0 code will mainly also need print() to print statement
If this is only about supporting "late 2.x" (i.e., 2.6 and upwards), you can already write:
People often do not specify. I suspect some are thinking back to 2.5, but that will change in the future.
i am the author of the original post quoted above. i wrote a parser library (lepl) using 3.0. backporting to 2.6 was fairly easy, but it still does not run with 2.5. if i remember correctly it appeared that i was going to need separate source files because of significant differences in syntax (print, exceptions) as well as missing functionality (metaclasses, string formatting). andrew
