The ast document states that Try/TryStar have an attribute of type excepthandler, not ExceptHandler. Also Module has of type type_ignore, not TypeIgnore.

Hmm, this doesn't look right. Where in the docs does it indicate this? Are you maybe going by the grammar at the top of the docs, and missed the definitions of type_ignore/execpthandler further down? E.g. type_ignore in the grammar stands for a TypeIgnore node:

    type_ignore = TypeIgnore(int lineno, string tag)

Looking at the nodes at runtime suggests that the current stubs are correct:

>>> ast.parse("# type: ignore", type_comments=True).type_ignores
[<ast.TypeIgnore object at 0x7000551b31d0>]

>>> ast.parse("""
... try:
...     pass
... except:
...     pass
... """).body[0].handlers
[<ast.ExceptHandler object at 0x7000551c8990>]

@brianschubert Thanks for the reply. It seems I misread the documentation. I'll close it.
