Subject: overlay showing computed value of macro?

I use macros in my course syllabi to automate creation of timestamps It
looksl ike this:

# see bottom of this email for the defn of ~get-ts~
#+MACRO: ts (eval (get-ts+7))


** Week {{{n}}} ({{{ts}}}): Time Scales in Rivers, Geology, and Human
Relationships
* Week {{{n}}} ({{{ts}}}): +READING WEEK: NO CLASS
** Week {{{n}}} ({{{ts}}}): Communities, States, and Water Governance

This makes it much easier for me to re-arrange headings while I'm planning
schedules.  But it's a little hard to tell, for instance, if I have the
right number of class meetings, or if the University holidays are in the
right place, etc.

It would be nice for me to overlay the macro invocations with the values
that they will evaluate to on export. I guess I would have to figure out
when to trigger recalculation of the values (maybe not too often, say only
when the macro is first created, when it's edited or deleted/deformed, and
perhaps on structure editing.

I do not understand emacs overlays very well so this feels a little
daunting to me.  Does anyone out there have ideas about how to do it
effectively?

Thanks as always!
