I think existing uses of the decorator markup rely on the reader’s understanding that it’s syntactic sugar for a call and an assignment, and they don’t have decorator+function markup.  The PRs for this ticket follow that.

That said, staticmethod as a non-decorator has an important use case for function injection in tests (using self.func in TestCase classes that work with a C module and an equivalent Python version).  Maybe this deserves an extra example?
