## Summary

Our `SoftKeywordTokenizer` only respected soft keywords in compound
statement positions -- for example, at the start of a logical line:

```python
type X = int
```

However, type aliases can also appear in simple statement positions,
like:

```python
class Class: type X = int
```

(Note that `match` and `case` are _not_ valid keywords in such
positions.)

This PR upgrades the tokenizer to track both kinds of valid positions.
