struct S { int* p, p2; }

int f() {
    assert(S().p == null);   // passes
    assert(!S().p);          // passes
    assert(S().p == S().p2); // passes

    auto s = S();
    assert(!s.p); // passes, note: `s.p` also passes
    assert(s.p == null); // fails
    assert(s.p == s.p2); // fails
    return 0;
}

int g() {
    auto s = S();
    assert(s.p);  // passes but should fail
    return 0;
}

void t()() { enum e = g(); } // const for D1

static assert(f() == 0);
// static assert is in a function because of @@@BUG3448@@@ aka @@@BUG965@@@
void f3448() { static assert(!__traits(compiles, t!()())); } // is(typeof())
for D1
