I think this is a great idea. In fact, when I do an intro to numpy, I spend
a bit of time on those issues, 'cause I think it's key to "Getting" numpy,
and not something that people end up learning on their own from tutorials,
etc. However, in my case, I try to jam it into a low-level intro, and I
think that fails :-(
So doing it on it's own with the assumption that participant already know
the basics of the high level python interface is a great idea.
Maybe a "advanced" numpy tutorial for SciPy 2017 in Austin also???
Here is my last talk -- maybe it'll be helpful.
the strides stuff is covered in a notebook here:

And Julian's temporary work lends itself to a very nice talk, more on
