I'm running into an issue with the syntax of https://www.python.org/dev/peps/pep-0589/

```
class C(TypedDict):
    to: int
    from: int
	
SyntaxError: invalid syntax
```

I'm not sure any change needs to be made to the specification.
But the interpreter needs to recognize that `from` is a string key to a `TypedDict`, not the keyword `from`.

Or if you don't want to have to recognize `from` as a string instead of a keyword, we need a specification that allows us to put keywords as keys in `TypedDict`.

I was thinking maybe something like:
```
class C(TypedDict):
	"to": int
	"from": int
```
as an optional way to write the same thing.
