          Issue ID: 15561
           Summary: std.typecons.Proxy gets NaN comparisons wrong
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW

Let's see it in action in std.typecons.Typedef:

alias MyFloat = Typedef!float;

unittest
{
    MyFloat a,b;
    assert(a!=b);
    assert(!(a<b));
    assert(!(a>b));
    assert(!(a>=b)); //fails
    assert(!(a<=a)); //fails
}
