Indeed. This is how I originally envisioned docstrings, and this is
how I still like to see them: short hints that mean you don't have to
look it up in the manual in most cases (if you have some common sense
and experience and aren't looking for how hairs are split in edge

> The primary/secondary splitting (not possible in CL), does

But note that there are other points of view. I don't mind if some
package author wants to keep all the docs together with the code and
wants to stick it all in the docstrings, and run some tool that
extracts the docs and formats them as a reference manual. That's just
not how I want to manage the standard library docs.
