spy's handling of multiline inputs might suit you better, although in this
case it doesn't seem like a characteristic of the interface as much as an
implementation detail.

On a completely different note, do you have any specific thoughts about how
the daemon mode is going to work? I considered it for spy, but getting it
exactly right is non-trivial:
- Multiple users on the same system should definitely work
- Different pythons or different virtualenvs under the same user should work
- Where should the daemon's stdout go?
- If `_` is present, what will happen when you inevitably end up working on
two things at once in different terminals?
- If this requires any manual help from the user, we've lost. It's not
convenient enough
