I started on something years ago but never got it working as nice as python,
as the guile debugger still needs some help to get there. Try this
snippet.
(define-syntax-rule (jump-to-debugger)
(if (eqv? 'regular (vm-engine))
(give-warning)
(start-repl
#:debug (make-debug (stack->vector (make-stack #t)) 0 "trap!" #t))))
You'll need some of this mess to resolve procedures:
(use-modules (system repl repl))
(use-modules (system repl debug))
(use-modules (system repl common))
(use-modules (system repl command))
(use-modules (system vm frame))
(use-modules (system vm vm))
(use-modules (ice-9 control))
(use-modules (ice-9 rdelim))
(use-modules (ice-9 pretty-print))
(use-modules (system base compile))
