This pattern (two closing braces at the same level) is why switch
scope
variable declarations were introduced (at least as far as
introductions
by me go). If switch scope variables aren't okay (which I continue to
consider questionable), then this stylistic aspect needs sorting
first
(if everyone else thinks the above style is okay - with the missing
blank line inserted -, then so be it).
Actually, they can be deviated because they don't result in wrong code
being generated.
Only later I recalled Andrew's intention to possibly make use of
-ftrivial-auto-var-init. While, unlike I think he said, such declared
variables aren't getting in the way of this (neither gcc nor clang
warn about them), they also don't benefit from it (i.e. they'll be
left uninitialized despite the command line option saying otherwise).
IOW I think further consideration is going to be needed here.

Well, in that case I'm happy if I can contribute in some way to the
discussion, but
perhaps this is best sorted out in a separate discussion, so that later
I can send a v2
reflecting the decision(s).
