People always come up with hacks like Ir. Robert Vanden Eynde has come up with
the vertical bar hack. This is why I feel there's no need to have additional
performance decrease and new syntax only to solve a little problem that occurs
in some third party like sympy.

This is my first time seeing the vertical bar hack. I guess this is
something that has appeared before?

Hello everyone, what is the usual way to "like" a mail in the maillist and
subscribing to the thread ?
By sending a message it adds me to the "Participants" in the webapp which
is neat (I can then search for my messages)
I could do it in the webapp but not everybody will see it

I'm +1 on the idea but -1 on the proposed syntax. Yes it would be kind of nice
*but* it's not how Python arithmetic or grammar works. And why should Python
have that functionality? AFAICT Python doesn't have a module in stdlib for
symbolic math. This looks like a feature request to third party
It's a neat idea but I agree with the others that as proposed, it's
probably too focused on turning python into a better mathematics tool,
rather than turning python into a better programming language.
That being said, from a more generalist standpoint I wonder if it would be
useful in many

Hi list,
as you might have noticed, I am trying to improve the syntax and semantics for
symbolic math in Python. Until now, I have to say, my ideas were not that well
received, but I learned from the discussion and maybe this time I come up with
something people like.
