Yes, that is how I solved it in LilyPond
(https://gitlab.com/lilypond/lilypond/-/merge_requests/1026).
I was also somewhat surprised to see that
record types are self-evaluating. I don't
know where to check in R6RS what the expected
behavior would be. At any rate, it seems that
there is an inconsistency between the interpreter
and the compiler that would warrant resolving
either way.
