I am unfamiliar with hi-lock.

Yeah, but there are recurring patterns, for example
those that I just fontified: interactive, compiled,
Lisp (sometimes "C"), function, etc. Here,
highlighting could be used just as anywhere to reduce
reading and increase seeing. Hand on the heart, when
you bring up the help, do you actually *read*
... is an interactive compiled Lisp function ...
I sure don't, so for me it is a small window of
improvement to have that colorized because then it
would enter my mind that way instead (more), and
I would still not read it.
For example, having "Lisp" in one color and "C" in
another would be cool.

Yeah, that sound reasonable.
