hi, 

Would it be possible to move to python 2.7 as the default (and even break 
feature parity with python2.6 to take advantage of 2.7 (OrderDict, etc))?

For the linux/mac landscape this shouldn't be a problem, as python 2.7 is 
available there (and sometimes even default).

Many projects still use python 2 (haven't shifted to Python 3.x), so it's good 
to stick there. Also, python 2.7 is the last stage of python2 series [1], so 
there won't be any python2.8. Also it's actively used, so there will be 2.7.y 
bugfix releases. That makes it ideal target.

Pros:
+drop hacks for py2.6
+reduce Travis build matrix
+python 2.7 is final stage of py2

Cons:
-Grok uses Jython, Jython depends on python 2.5(?) (EDIT: I learned it doesn't 
anymore)
But now there seems to be a release using python 2.7 (albeit beta!) [2], would 
it be possible for grok to shift over to using it?
