This also improves the documentation in the following ways:
- Clarifies that `eval` requires no annotations.
- Clarifies that `eval_ordered` ignores annotations.
- Clarifies that `eval_ordered` does not work with matrix returns
(which could very well be created by instant queries).
- Clarifies that there are more `eval` commands than just `eval`.
- Improves wording for `eval_ordered`.
- Replaces `...` by the typographical correct `…`.
- Fixes a numerical error in an example.
