I don't yet know what this means in detail, because I've never looked
at how hippie works.  I'll take a look soonish, but if you happened to
work it out for me first I shouldn't mind!

I completely agree as regards reloading, and I'm sure from my own
experience that it is a frequently useful usage pattern.

The implementation is just "load the relevant file", I believe; the
only slightly tricky part is working out the most convenient possible

I'm not sure about unloading.  I don't recall ever wanting to do it in
practice, and I'm not sure Guile has any way of achieving it.
