Isn't this what lilypond-book does already?

When for example you create an

@lilypond[verbatim,relative=1]
...
@end lilypond

It outputs the real output but also with the verbatim gives you the 
'code' as well which we use in the docs.

Now that doesn't mean that it translates straight to a SCM function (to 
make youre \example function) but if you look in the source in 
$LILYPOND_GIT/python/ all the various book* py files I think would give 
you clues.
