The python plugin is broken

[kyakovenko]

Hello guys,

It seems the 348026a has broken the python plugin because it can no longer handle function calls, e.g. an indexing of the following example:

import collections
Person = collections.namedtuple('Person', 'name age gender')

produces next output:

Traceback (most recent call last):

Specifically, we now have problems with method calls. @jbradberry pointed this out Friday and is working on a fix. Thanks for the report!
