           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW

The following currently fails for const variables:
```
    const CustomFloat!16 x = CustomFloat!16(3);
    assert(x.get!float == 3);
    assert(x.re.get!float == 3);
    assert(x + x == 6);
    assert(x + 1 == 4);
    assert(2 + x == 5);
    assert(x < 4);
```
