Cannot have properties on const references?

[simendsjo]

Sorry about the possible double post. I cannot see my previous..
struct S {
    @property int B() {
        return 1;
    }
}

void main() {
    S s1;
    auto a1 = s1.B; // ok
    const(S) s2;
    auto a2 = s2.B; // Error: function t.S.B () is not callable using 
argument types ()
}
