Research direction

Search the specification for each use of the term "concrete type" and read the surrounding definitions and examples. Determine whether the intended meaning is a type specified by a Python class name, then define the term consistently or replace all usages; done means the specification no longer uses the term ambiguously.

Description

topic: typing spec

This term is used in a few places in the spec, but never defined. I think it is intended to mean "a type specified by the name of a Python class." We should either give a clear definition for the term, or replace its usages.
