I would like to be able to use a `yield from` expression in a

statement without parentheses, as a small quality of life tweak, i.e.:
return yield from gen

return (yield from gen)
What does this do? `return (yield …)` is the expression form, so this
generator is really a coroutine, but unless I missed it your gist
doesn't have a `.send` or `.throw` and you aren't using the value of
StopIteration.
So I think your idea is really to create a shorthand for
```
yield from gen
return
```
Is that what you mean? or if I misunderstand please explain further.
In my example, the return value (StopIteration value) of the generator
is the function which will handle the next character in the lexer. The
value of a `yield from` expression is the StopIteration value.
