I'm closer to a hobbyist than a professional dev, but the async views seem like a big functionality. Having done some Django apps, getting a synced up view for some changing variable was always a bit painful.
async def current_datetime(request):
now = datetime.datetime.now()
html = '<html><body>It is now %s.</body></html>' % now
return HttpResponse(html)
seems like an example that I was thinking of.
