Then, what's wrong with quoting? It's just 2 characters, and prevent the
user (or their IDE) from trying to parse them as Python syntax.
Informal user research has shown high resistance to quoting.
As a comparison: docstrings do get quoting, even though they also have
special semantics in the language.
Not the same thing. Docstrings use English, which has no formal (enough) syntax. The idea for annotations is that they *do* have a formal syntax, it just evolves separately from that of Python itself.
