A big thanks to the Organizers and Reviewers for letting me speak. This kind of thing encourages me to work on projects like this.
 * https://github.com/rocky/python-decompile3 : Much smaller and more modern code, focusing on 3.7 and 3.8. Changes in that will get migrated back here.
 * https://code.google.com/archive/p/unpyc3/ : supports Python 3.2 only. The above projects use a different decompiling technique than what is used here. Currently unmaintained.
 * https://github.com/figment/unpyc3/ : fork of above, but supports Python 3.3 only. Includes some fixes like supporting function annotations. Currently unmaintained.
