"from collections import ChainMap" fails after "install_aliases()"

[wcooley]

According to the last example in the "Aliased Imports" section in standard_library_imports.rst and for 0.15.2, this should work:

Python 2.7.11 |Anaconda 2.3.0 (x86_64)| (default, Dec  6 2015, 18:57:58)
[GCC 4.2.1 (Apple Inc. build 5577)] on darwin

Thanks for reporting this, Wil. I have added a patch to the v0.16.x branch to add ChainMap to collections. Could you please try this and report back?

I experienced the same issue, on v0.16.0, but the one, on the branch v0.16.x, is working now.

This hasn't been fixed and released? Your docs still say ChainMap is available.
