My recent macro-importing changes have caused a problem.
Previously, imported macros always put the returned value through
`lispref->scm'. Now they make Lisp references just like imported
functions.
(define-module (emacs user)
:use-module (emacs import)
:use-module (emacs macro))
(begin-save-excursion 1)
=> #<procedure-with-setter>
I don't think we want a Lisp reference in this case. The easy
fix would be to make imported macros call `lispref->scm' again,
but that might be wrong for some macros. And it gets worse:
(define lr (object-property (begin-save-excursion 1)
'lisp-reference))
lr
=> #<lisp-reference>
(import-lisp-function prin1-to-string)
((prin1-to-string lr))
=> "#<scheme_reference>"
So we have a Lisp reference pointing to a Scheme reference.
I think make_lispref should return the original Scheme object
instead of making such double references. May I change it?

Yes, please. And the new internal implementation which I plan will
solve all this kind of problems anyway. Could you implement it?
(I have to learn the GOOPS's C interface before doing that.)
