Hi Sean and Yasuo I agree that they are somehow related, but I also think (and I might be wrong) that the behaviour of the Multi-Catch is obvious and I don't see how this syntax/feature could be interpreted otherwise. The multi-catch don't have any open-issue that the Union-Types have like weak types since it only deals with Exceptions. Also, we still don't know if we'll one day have the Union-Types since there are those open issues and it would be sad to wait something that could never append. It's IMO pretty safe going forward and if required in the future change the implementation when needed (Behaviour will stay the same, unless you see other behaviour that this syntax could have in this same "catch" context).
