Nope.
Why is zoo*zoo nan?
In [71]: zoo*zoo
Out[71]: nan
It seems to me that the result should just be zoo.

It may be possible to get that username, since there is only one tweet and
that is our official name. I wonder what their policy is on this.

I sent an "impersonation claim". Based on

will likely get it since @sympy has been inactive since 2009.

zoo is complex infinity (i.e., S.ComplexInfinity). See

In that case, zoo*zoo is zoo. No ?

Yes, I believe it should. That's why I'm wondering why it gives nan.

Sympy's subs function does not seem to be able to recognize negative
multi-term expressions...
x,y = symbols('x,y')
e1_, e2_ = symbols('e1, e2')
e1 = x
e2 = 1+x
[(e1).subs(e1,e1_), (-e1).subs(e1,e1_), (e2).subs(e2,e2_),
(-e2).subs(e2,e2_)]
produces:
[e₁, -e₁, e₂, -x - 1]
Is there a reason wh

Can someone explain why it's trying to mess with the frame? This is
very fragile, and very rarely needs to be done.

No, but Python is a good source, as the project goal is to build on
top of it using the same rules. So if a Python built-in equivalent
exhibits some behavior, we should emulate it (except in the cases
where we try to do better, like arbitrary precision vs. machine
precision).
And anyway, Python f

I would highly recommend changing this. Use of such hacks are, as I
said fragile, and un-Pythonic. var() is only intended for interactive
use. It's fine to have a similar function for interactive use, but
the main API should use regular name assignment.
Note that even var() doesn't always "work
