scheme memory address

Suppose I write #(define x '(1 2 3)) is there any way in scheme to print the memory address where x is pointing to? (where is allocated the first element of the list) Thank you, g. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gn

Ciao Harm, Andrew, Aaron and David, this is what I have been able to do adapting Harm code: \version "2.21.0" foo = #(let ((x '(1))) (define-scheme-function (arg)(symbol?) (case arg ((incNumber) (set! x (append (drop-right x 1) (list (1+ (last x)) ((unindent) (drop-right! x

Hi Aaron, I beg to differ. Here plain and clear from the start of the R5RS Scheme specification is the following: Arguments to Scheme procedures are always passed by value, which means that the actual argument expressions are evaluated before the procedure gains control, whether the procedure nee
