Won't he stop doing videos in like a week?

The reasoning does not seem that convincing. I also don't create new instances from the Manager but instead use the normal constructor like this:

instance = models.MyModel(...)
# instead of something like
models.objects.create(...)

So I would want alternative constructors in the same place...

That's really cool. I've been thinking about doing something like that for pathfinder to. I wonder how it works with copyright and stuff. Did you upload the rule PDF to it?
