The list * operator isn't the most heavily used operator, but it does get
used a bit. It comes up quite f

With my suggestion, we get:

Hi.
I've put some thoughts together, and
need some feedback on this proposal.
Main question is: Is it convincing?
Is there any flaw?
My own opinion - there IS something to chase.
Still the justification for such syntax is hard.

Correct. Let's say you want to make a 1-D list with three items
initialised to zero. This works brilli

break doesn't exit the function, it exits the loop. There is no loop to

The print statement in cases 3 & 4 reports the following:
