Well, I would have no problem to c/p 'parse-simple-duration', though
yes, it is possible:

#(define (note-to-moment notestr)
    (let ((parsed ((@@ (lily) parse-simple-duration ) notestr)))
         (ly:make-duration (car parsed) (cadr parsed)))))

#(write (note-to-moment "4."))

--> #<Mom 3/8>

Though, quoting guile-manual:
— syntax: @@ module-name binding-name
Refer to the binding named binding-name in module module-name. The
binding must not have been exported by the module. This syntax is only
intended for debugging purposes or as a last resort.



Part of the problem with copy and pasting was that it didn't work. I got the final piece of the puzzle though by Mark.

I would still prefer this solution, but what you're saying is that it isn't really suitable to use this kind of syntax and that it is better to copy-and-paste!?
