Principle is important. eev can be embedded in text, the following
link may be evaluated with M-e and point being anywhere before the
sexp:

This is line before the sexp (find-man "man")

But I think it should also work after the sexp. And the sexp could be
underlined visually. In one way is similar to GNU Hyperbole buttons.

It is useful for instructions.

1. Do something (ok I will do)

2. Do more (ok-here is more)

And I have it similar in combination either with eev or GNU Hyperbole:

1. SLIME: The Superior Lisp Interaction Mode for Emacs (hyperscope 37269)

2. Handle the Magic Keywords File List (hyperscope 35956)

It jumps quickly to the note or item that I need. Numbers are used. I
could as well use: id:35956 

It then jumps to the list here:

 37272 Introducing Linux Air Combat                                           WWW          
 37271 SLY User Manual, version 1.0.42                                        WWW          
 37270 Emacs Lisp Introduction                                                WWW          
⧓37269 SLIME: The Superior Lisp Interaction Mode for Emacs                    WWW          
 37268 Functions | Common Lisp                                                WWW          
 37267 Read–eval–print loop - Wikipedia                                       WWW          
 37266 PostgreSQL: The world's most advanced open source database             WWW          

But it could as well open it, instead jump to the heading. It could
jump to edit the note, or to read the PDF, or watch movie. Only that
attributes are defined in the object itself, not in the Lisp
function. 

The list of items can be generated, in fact I generate Org file with
hyperlinks out of all nodes.
