Hi,
I have a program that uses multiple threads and may have several exceptions
happen more-or-less at once. I'd like to be able to raise them all together and
have all of them printed to stderr, including stack traces.
I first tried just throwing them in a list and raising the list, but of course
that doesn't come out very pretty (only one thread failed in this example):
uncaught exception: (list (exn:fail:task-failed "I failed.\n"
#<continuation-mark-set> ...))
Next, I thought I'd try looping through the exceptions and using exn->string.
But it seems this function doesn't give me stack traces or any kind of source
location information.
It occurred to me to try to use the same mechanism that the REPL does, but I
don't know anything about it, and I found the documentation on prompts and
aborts to be a bit confusing. I didn't grok how the REPL used them to pull off
its magic trick. What's the right way to go about this?
Thanks,
Lucas
