[Typing-sig] Status of PEP 645? (Allow writing optional types as x?)

30 Mar 2022


      The typing-related PEP 645 - which introduces the syntax `T?` to mean 
`Optional[T]` - only has a single substantial related commit in the PEPs 
repo - the commit introducing the PEP (in Nov 2020) - and no discussions 
thread that I can find (on typing-sig or elsewhere).
I'm personally quite interested in the potential capability to quickly 
signify `Optional[T]` since it is something I do a lot.
What is the status of this PEP? Deferred for now? Withdrawn in favor of 
`T|None` syntax?† Something else?

† Through the grapevine I've been inferring that folks have been 
gravitating toward the slightly-shorter `T|None` syntax to spell 
`Optional[T]` in the meantime, and I even mention that spelling in my 
own PEP 655 (Required[]) [1]
