Now that Python is beginning to embrace type annotations, is it worth
revisiting the idea of having extended integers and an integer infinity?
I found myself trying to annotate this line:
events_to_do: Union[int, float] = math.inf
where I am only including float in the union to accommodate math

Folks,
Can I please remind people to trim their quoting? We readers shouldn't
have to hit the Page Down key eight or nine times, or scroll down
through five or six pages, to see the first new content.
(I have a rule: if I haven't reached new content after nine screens of
quoting, I give up and
I think
print("Remember to wear sunscreen!") if hot_outside unless Weather.is_raining()
Is more readable than
if hot_outside and not Weather.is_raining(): print("Remember to wear
sunscreen!")
I think the unless syntax would be especially useful when there is a series of
functions like this.

I'm concerned that in this thread, and elsewhere, we're not paying
sufficient attention to https://en.wikipedia.org/wiki/Cognitive_load.
Adding a feature to a system can increase the cognitive load in

using the system. Sometimes add
