Yeah, and languages like C# solve these problems quite
beautifully. I don't think there's a reason we can't do almost
the same thing in D, except it requires implementation effort and
overcoming Walter's protests. Regardless, it's probably not
something to expect in the short-term.

I was unable to leverage std.exception. collectException looks
promising at first glance - and maybe if the return value and out
parameter were switched, it would work - but then I suspect the
function's implementation would face exactly the same problem.
