[New-bugs-announce] [issue3051] heapq change breaking compatibility

[Thomas Herve]

New submission from Thomas Herve <therve at free.fr>:

A recent change in heapq implements it in terms of less-than:
http://svn.python.org/view/python/trunk/Modules/_heapqmodule.c?rev=63827&r1=63675&r2=63827

Unfortunately, it breaks usage of heapq when a class only implements
__le__ and not __ge__ or __cmp__. This is done this way in Twisted:
http://twistedmatrix.com/trac/browser/trunk/twisted/internet/base.py#L159.

If not mandatory, it would be nice if this change was reverted or that a
backward compatible change was done instead.
