Hi. Ondrej will probably have better answers to your questions when
he replies, but here is my take.

Aaron's replies are excellent. Some comments below:

Thank you for this - I am studying it and it definitely has some of
the flavour of what i'm thinking of. Once I understand it better I
can say more.

Hi Ondrej,
Thanks for your message and for your original talk. Let me just make a
couple of quick comments and I'll try to be more complete later.
It is not clear to me how the object representing a vector space
should be set up. But something like what you suggest seems right.
For example:

Hi Aaron,
The Set class is important to have as a master class for all kinds of
other classes which should exist, such as Group, Field, Vector space,
Algebra, etc. As it is in Category theory.
A Python set may indeed be a good place to start, but as you suggest,
it would only be a finite set of

Hi Aaron,
Can you explain the thinking behind the Symbol class? I looked at the
doc string but it's not clear how general this kind of object is.
Thanks

I have worked around with Mul and Add, so I know pretty well how they
work, but I haven't worked with Symbol as much. Ondrej and others who
wrote the core will know much better. Also, is there a specific class
that you are considering if it should be a subclass of Symbol?
