I've literally never written a finally block in my life in D because scope
statements and RAII are just that good. Does anyone, other than a few beginners
who were unaware of scope guards, use finally? I'm half-tempted to say we should
just axe it. It's an error prone legacy feature that's completely useless for any
purpose except writing Java or C# code in D. Since we're looking to lighten the
spec, ditching finally would do so, and it would encourage converts from Java and
C# to learn a better way of doing clean-up code.
