DMD can implicitly convert class pointer to the bool. Is it bug or terrible feature?

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.
