           Summary: "==" causeses error for array of classes in safe
                    method
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW

The following code compiles:

class C { int a; this(int) @safe {} }

void main()
{
    C c = new C(1);
    C[] a = [c, c, c];
    assert(a == [c, c, c]);
}

The following code fails:

class C { int a; this(int) @safe {} }

@safe void main()
{
    C c = new C(1);
    C[] a = [c, c, c];
    assert(a == [c, c, c]);
}

with the message: incompatible types for array comparison: `C[]` and `C[3]`
