[$] Wrangling the typing PEPs

When last we looked in on the great typing PEPdebate for Python, back in August, two PEPs were still beingdiscussed as alternatives for handling annotations in the language.The steering council was considering the issue after deferring on adecision for the Python 3.10 release, but the question has beendeferred again for Python 3.11. More study is needed and the councilis looking for help from the Python community to guide itsdecision. In the meantime, though, discussion about the deferral has ledto the understanding that annotations are not a general-purpose feature,but are only meant for typing information. In addition, there is a growingrealization that typing information is effectively becoming mandatoryfor Python libraries.
