Python 2.6 does not have WeakSet about music21 HOT 2 CLOSED

I will need to update the Python Package Index — unfortunately the information is out of date. Music21 since, I believe 1.8 or 1.9 requires Python 2.7. The only thing that was added in 1.9 is the functionality for speed that WeakSet gives so a shim to continue to support 2.6 will not add new features.

Best,
Myke

Python Package Index states 2.6 as supported in Music21 1.9.3, https://pypi.python.org/pypi/music21.
The Python class weakref.WeakSet is used in streams.timespans: https://github.com/cuthbertLab/music21/search?utf8=%E2%9C%93&q=WeakSet

WeakSet is introduced in Python 2.7.

Easy to test with Python 2.6:

from music21 import *
stream.timespans.makeExampleScore()

This will result in exception: AttributeError: 'module' object has no attribute 'WeakSet'
