Re: [Python-ideas] Repurpose `assert' into a general-purpose check

• I'm opposed to making assert substantially different from the way it works now

If sometimes we will change assert I would prefer to make it more similar to assert in pytest. Output values of the final and intermediate expressions. The hardest problem -- the repr can be very long and expensive, we need an alternate protocol for producing a shortened representation.

• I'm in favour of adding a new "ensure()" builtin that encapsulates

the check-and-raise logic

Then may be add a new "die()" buildin? ;-)

0 <= r < abs(y) or die()
