What is actually the reason that we stick to this C90 rule?
Is it because of compability with ancient compilers? (Given that we
already require several C99 features, I doubt that there are compilers
which would fail if we stopped adhering to the
declaration-before-statement rule.) Or is it because it is presumed that
it improves clarity and readability?
