Guido van Rossum <guido at python.org> added the comment:
Before we backport this to 3.7 and 3.6, let's iterate on the wording a bit.
I don't think the distinction between annotations and type hints is that annotations are materialized at runtime while type hints aren't. I think syntactically they are the same, but annotations are a slightly more general concept because they may be used for other purposes than to indicate the type of a variable (or argument, attribute etc.).
So IMO in
'int' is both an annotation and a type hint, OTOH in
x: 'spam eggs ham'
we have an annotation that is not a type hint.
