[New-bugs-announce] [issue24660] Heapq + functools.partial : TypeError: unorderable types

[Марк Коренберг]

New submission from Марк Коренберг:

>>> import heapq
>>> from functools import partial
>>> qwe = [(0, lambda x: 42), (0, lambda x: 56)]
>>> heapq.heapify(qwe)
>>>
>>> qwe = [(0, partial(lambda x: 42)), (0, partial(lambda x: 56))]
>>> heapq.heapify(qwe)
Traceback (most recent call last):
  File "/usr/lib/python3.4/code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
TypeError: unorderable types: functools.partial() < functools.partial()


So it is not realiable to use heapq if element of the array is (int, callable)
