          Issue ID: 21889
           Summary: __traits(isSame, Object, const Object) yields true
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: andrei@erdani.com

This code fails:

static assert(!__traits(isSame, Object, const Object));


The issue seems is not particular for Object and const Object. These fail too:

struct S {}
static assert(!__traits(isSame, S, const S));
class C {}
static assert(!__traits(isSame, C, const C));
