Warning
At present, this is not much more than a copy of the CPython original with the obviously inapplicable crudely hacked out.
There's more to changing Python's grammar than editing :file:` grammar/Python.g`. For a start, we only do this in order to track a change developeed on the reference implementation CPython. This document aims to be a checklist of places that must also be fixed when such a change is adopted by Jython.
It is probably incomplete. If you see omissions, submit a bug or patch.
