It seems this would still require parsing. Is there any way to get
the arguments themselves, as plain Scheme values instead of text?
frame-arguments sounds promising; I'm just not sure how to use it. I
tried this:
(make-stack (call-with-current-continuation identity))
But got a segfault. Dunno if that was supposed to do anything useful;
I was just messing around.
