Just for clarification, the code that I posted above is just some very
preliminary experimentation I had been doing on my own machine. It

I've attached the _very_ rough version I started awhile back. It just
does FormalPowerSeries and DataStream.

Hi Dan,
I've been spending a bit of time with symmetric functions recently.
In the near future, I'll be making a commit that adds support for
Hall-Littlewood, Macdonald polynomials, and quasisymmetric functions.
Other stuff that will need to be done are LLT polynomials, k-Schur
functions, and non
By the way, what other sorts of combinatorial functions need to be
written? I'm pretty decent with Python, Mathematica, and Maple, and
would be happy to help out. I don't really do graph theory, though, so
the recent post here on graph theory stuff is not something I'd be
very helpful with.
