I've wasted more time than I should've the past few days trying to understand what this message means. At a minimum the documentation should be updated, but preferably the error message itself should be clarified. The example on https://docs.perl6.org/language/traps is not entirely clear, and did not at all match the scenario I was hitting. The provided stack trace also fails to point to the source of the issue. A trivialized example: say "Test await after fulfillment"; my $p = Promise.new(); my $vow = $p.vow; $vow.break(1); await $p; Results in: An operation first awaited: in block <unit> at ../test.pl6 line 5 Died with the exception: 1 in block <unit> at ../test.pl6 line 5 This haiku-like message simply means that the Promise/Vow has been broken. Farther, the exception points to the "await $p" line, when it's really the "$vow.break" line that's responsible for the trouble. I'd suggest a better error message in this case (if possible) would be something like: *A Promise was broken by ../test.pl6 line 4 awaited upon* in block <unit> at ../test.pl6 line 5 Died with the exception: 1 in block <unit> at ../test.pl6 line 5 Just trying to do my part to make Perl6 better ;-) - David
