AFAIK, there is no way to detect whether an exception is in flight or not
aside from the cases where scope(failure) or catch would catch the
exception, and from what I recall of the last time that someone asked this
question, the consensus was that it couldn't be done - but maybe I'm
remembering incorrectly. I am pretty sure that this was asked within the
last few months though, so if you search D.Learn, you can probably find that
discussion.
