8546 :: How do you get the actual exception from doAssertRaises?

  In my tests I want to test that exceptions are correctly raised at certain points - but how do you get access to the raised exception object so that you can e.g. make assertions about its message / any other attributes? My Google-fu seems to be coming up short ...

  Not that you need std/unittest but this is a faux example of what you might want to do.

  import std/unittest
  type YourException = ref object of CatchableError
    a: int
  suite("Test"):
    test("a"):
      try:
        raise YourException(a: 300, msg: "hello")
      except YourException as e:
        assert e.a == 300
        assert e.msg == "hello"
  Run
