Simple issue. When doctest runs, it uses some colored text. If further information is printed after doctest runs, then the rest of the text is all red. Not a huge issue, but I thought I'd report it.
[doctest] run with "-dt-help" for options
[doctest] test cases: 2 | 2 passed | 0 failed
[doctest] assertions: 10 | 10 passed | 0 failed
------ everything below here will still be red ------
