And did you actually look at the linked patch?
Not when I wrote that note.
I looked at http://www.phas.ubc.ca/~eviatarb/?e=11
If this is what dlmf is supposed to be upgraded to include, that's what
I was complaining about.
On your prompting, I looked at, for example,
http://trac.sagemath.org/ticket/2516
which indeed comments on some symbolic manipulation. It looks like some
was done 3 years ago, and
is in various stages of incompletion. Perhaps characterization of what
you can do is in order, rather
than requiring searching through patches and finding out if you include
(say) differentiation,
simplification (if so, how much), arbitrary precision evaluation,
interaction between simplification and assumptions,
solve, etc.
