I've read and reread the parts of the C++ standard, and I've just ended
However I'm finding it hard to read this as saying a new scope is
created and entered.
int a, b;
b is "in scope" from the character 'b' but you don't enter a new scope
when you see the 'b'.
In comparison C99 is very explicit that a whole new scope is created,
as is C++ for the controlled statements. So I don't see it for the
outer statement in C++.
This matters with, for example,
if (int x = 1)
where I read the C++ standard as requiring a redefinition of x
