Comment (by Tarrasch):

 Hi Carter,

 Implementing stack traces can be thought of two parts, (1) the code-
 generator stuff that now has to be able to also emit debug data and (2)
 Library and rts components. Peter is working on the (1)-part, his most
 recent work is here[1] (afaict). I work on the (2)-side of things. My work
 is here[2].

 But I think the most interesting parts is the research and conversations
 we're having. Peter and I are usually collaborating at least weekly on
 this. I'll be more than happy to share or explain any detail you might be
 interested in.

 thing you reminded me)
