Yes.

Not necessarily.  This expansion would be a possible implementation
right now, but in the end, it is probably better to make a new
'primitive' syntax for identifiers.  Consider a syntax-case definition
of '::'.  It would have to expand into something like

 ((:: (guile) module-ref) ((:: (guile) resolve-module) '(my module)) 'start)

since it needs to fix the references to 'module-ref' and
'resolve-module'.  So '::' or something equivalent is needed for the
output of the macro expander itself.  In the new-model.text, I have
used keywords for things like this.  '(:: MOD VAR)' could simply
expand into

  (:module-ref MOD VAR)

in the 'new model'.
