Do you agree? It would be useful for:
In [10]: x.subs(Eq(x,1))
---
ValueError:
When a single argument is passed to subs it should be an iterable of
(old, new) tuples.
In [11]: x.subs([Eq(x,1)])

Although we honor "left" and "right", there is nothing strict about

That is true... I am just very confused by all the different ways that
the solvers return their solutions. Is there any convention about
that? When it is a list, a dict, an Eq...

I thought this too, but the consensus was to make it not do it. For
example, what would (x + y).subs(Eq(x, y)) return? See

What about making Eq iterable? It will permit the use of zip on a list of Eq.

Never mind, you agreed not to do it on the issue page.

For m
What you need to consider is if Eq is really an iterable container or
not. You can always convert it to one--or indeed, any Basic object
into one--using .args. It's also straight forward enough to combine
this with list comprehensions for functions like zip().
Personally, I don't think it is, but
