Well, those symbols are somewhere in between "public" and "private".  As
a user you shouldn't fiddle with them (unless you know what you're
doing).  If anyone wanted to implement a subclass elsewhere, they
certainly would have to add methods to some '--' symbols.  But then the
burden of keeping up with changes in drepl.el is on them and not me.

I suppose that's what people understand by double-dashed symbols...?

Ah, sure, that's what I should do.
