So no need to target a very specific version of Python.
I think this is suboptimal, having to guess where modules are located,
you end up with this in every module:
try:
import cjson as json
except ImportError:
try:
import simplejson as json
except ImportError:
import json as json
It's trivial to wrap in a function though - or do the import in one
place and then import the package from there.

Perhaps the versioned import stuff could be implemented (whatever the
syntax may be), in order that something like this can be done instead:
import regex('__preview__')
import regex('3.4')
Where clearly the __preview__ version makes no guarantees about
interface or implementation whatsoever.
etc.
