Comment(by SimonKing):

 I see that the problem is in sage.misc.sageinspect.SageArgSpecVisitor. It
 can analyse various types of abstract source trees -- this is implemented
 in the `visit_*` methods, for `*` in `List`, `Tuple`, `Dict`, `Num`. But
 `* == BinOp` is missing, and would be needed in the example.

 The generic `visit` method from the `ast` module has a bug, I believe: It
 returns `None`, and this is the `None` that we see as key of the
 dictionary that is the default value of b in the example above.

 I am now trying to add that, and also for the `UnaryOp`. However, the
 question really is whether it would be worth the effort...
