Hi there, Recently I have been working on an implementation for PEP 604 (https://www.python.org/dev/peps/pep-0604/). While working on this, I started reviewing and exploring what new Optional syntax would look like in the Python language. I've written a rough draft of a PEP and wanted to present it to this email list before submitting a PR. I know this is a topic that has been discussed in many settings (Github issues, in person typing meetups, etc. )previously, and wanted to solicit feedback here first. Let me know if submitting a PR would be a better way to gauge sentiment and feedback on this proposal. Draft Proposal (branch compare): https://github.com/python/peps/compare/master...MaggieMoss:optional-syntax-p...
