Can we incorporate this file into ordered_dict.py? I'd prefer there to be just a
single file with an OrderedDict class and I suppose these few little helper
method(s) (like Parse - would be nice to have that as a method on OrderedDict
but might be a contrivance to do so).

... import json_comment_eater

try:
  from collections import OrderedDict

  # Successfully imported, so we're Python >=2.7, and json.parse
  # supports object_pairs_hook.
  def Parse(json):
    return json.loads(json, object_pairs_hook=OrderedDict)

except ImportError:
  # Failed to import, so we're Python < 2.7, and json.parse doesn't
  # support object_pairs_hook. simplejson however does, but it's
  # slow. We also need to provide our own OrderedDict implementation.
  warn("using simplejson, so this will be slow!")
  ... import simplejson

  class OrderedDict(object):
     ... contents of ordered_dict.py goes here

  def Parse(json):
    return simplejson.loads(json, object_pairs_hook=OrderedDict)

Done.
