My reaction is that this was a user mistake of the same kind as accidentally writing `x + 1` instead of `x += 1`. That's just going to happen, very occasionally. (Though why? The ':' and '=' keys are not that close together.) Read your code carefully, or in an extreme case step through it in a debugger, and you'll notice the mistake. It's not a reason to pick on that particular syntax, and not much of a reason to try and introduce a mechanism to disable type hints. Sorry. PS. This particular syntax was introduced by PEP 526, and introduced in Python 3.6. -- --Guido van Rossum (python.org/~guido)
