It certainly is a good addition, but wouldn't it be better to add an
orthogonal argument for the "exports" stuff, that is a second parameter?

I mean: you've added `non-export' which maps to:

- `yes' for interactive evaluation
- `never' for export

I'm sure a guy (or a woman) will ask in a short future for:

- `query' for interactive evaluation
- `never' for export.

Hence, maybe we should be able to set 2 possible behaviors[1] for the `eval'
parameter:

- one for the interactive mode (yes/query/no), and
- one for the export mode (yes/no, and maybe query as well?).

Best regards,

[1] Like for results, where we can give up to 3 options:
    `:results output scalar raw'
