People haven't adopted this, and this is pretty annoying.
A similar case are commands bound to menu items (or any other keys): C-
h k does not bring up something useful for keys that are just bound to
a lambda term.
As for hooks, is a lambda expression ever suitable to be added to a
hook?
Would it make sense to change add-hook such that only true function
names are allowed?
