Could you explain how Maggie's proposal (writing 'int?') would conflict with Pablo's proposal? IIUC Maggie's proposal would require 'int?' to become a valid expression.
(As I expressed in the typing-sig thread, I'm lukewarm about 'int?' because we will have 'int | None'. The same reasoning applies to '?int' FWIW.)
Well, Maggie's proposal says that int? would be a typing-specific
syntax: "Should PEP 505 be approved in the future, it would not
interfere with the typing specific ?
proposed in
this PEP."
My concern was just that Pablo's proposal (as I understand it)
would mean there are no typing-specific expressions.

I think this would conflict with https://bugs.python.org/issue41967, where Pablo suggests moving the annotations into the parser. Annotations would then need to be valid expressions, if I'm reading it correctly. It's probably possible to work around this, but I'm not sure what it would take.
