Thanks Andy, this is looking great! There are one or two little points about typos and error messages, but once those are resolved, let's get this merged 😄

Thanks for the review @bcdickinson. All of those bits should be resolved now, and I have also added a CHANGELOG entry.

Great, thanks Andy. Looking forward to using this!

I’m trying to use this now and can’t get it running – there doesn’t seem to be anything loading the pattern_contexts files so the context modifiers can be registered, unless I’m missing something.

I have pushed my work-in-progress here: #146.

Moving the code from pattern_contexts.py to urls.py seems to do the trick, so it looks like the only problem is the pattern library missing some code to load those pattern_contexts modules.
