This is identifiers shadowing issue. In best case you could
not define boolean f, so the problem would not arise in a

Is it right for with to not give an error here?
struct Foo { int x; }
int x;
void main() {
Foo f;
with (f) {
x++;
}
}
Silent shadowing of global (module-level in both Python and D)
names has caused me many problems along the years.

Yes, it is confusing. It is especially confusing in an unstable
language with absent adequate spec. For example, I can learn C
namespace rules, but in D case it is useless. Unfortunately what
is right in cases like above depends on what Walter & Andrei
think so we stuck with their opinions on the subject.
(I think emitting at least warning would be good)
