Comment #11 on issue 2006 by [email protected]: Make all expressions
recursively callable
http://code.google.com/p/sympy/issues/detail?id=2006
The issue with that is like I said at the end of comment 5 (the a = ..., b
= ... part). Sometimes things will be callable and sometimes they won't,
and it will be easy to go from things that are to something that isn't. As
you said, you'd have to catch the error. At that point, you might as well
just use the helper function directly.
It looks like there are test failures outside of diffgeom. My guess is
that the series one is a typo/bug of some sort. I'm not sure what's going
on in the quantum module.
