\version "2.24.1"

floating-markup = #(define-scheme-function (parser location x y obj)
(number? number? scheme?)
                                  #{
                                    \markup \with-dimensions #'(0 . 0) #'(0
. 0){
                                      \override #'(baseline-skip . 0)
                                      \translate #(cons x y)
                                      #obj
                                    }
                                  #})


% GOOD
\floating-markup 15 -60 "some string"

% ERROR
\floating-markup 15 -60 \markup \circle #1

%%%%%%%%%%%

Doesn't seem to compile this way. Did I miss something?

Thanks
