           Summary: AAs broken for Object keys and values with opEquals
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: druntime
        AssignedTo: nobody puremagic.com
        ReportedBy: code klickverbot.at

Didn't fully track it down yet, but the following program asserts in getImpl
(mtype.c, line 4371) because AssociativeArray!(Object, TickDuration) can't be
instantiated (DMD 2.058 Git):

---
struct TickDuration {
  bool opEquals(ref const TickDuration rhs) const {
    return true;
  }
}

void main() {
  TickDuration[Object] aa;
  aa.keys;
}
---

Having a look at the gagged errors, it seems like the cause is related to the
opEquals const correctness issue:
---
Error: function object.opEquals (Object lhs, Object rhs) is not callable using
argument types (const(Object),const(Object))
Error: cannot implicitly convert expression (this.key) of type const(Object) to
object.Object
Error: cannot implicitly convert expression (p.key) of type const(Object) to
object.Object
---

The error is encountered while generating the default opEquals for the Slot
type added in
https://github.com/D-Programming-Language/druntime/commit/cd7b477b83cc8a75a90258bd2ab63fa8c92ba10b.

It works for me, but I added a test case for it anyway to the test suite.

Seems to WORKSFORME now as well, not sure when it was fixed or what the problem
was before…

Ah, screw it, now the auto-tester fails because of it as well:
http://d.puremagic.com/test-results/test_data.ghtml?dataid=146136. Must have
inadvertently introduced a workaround in my original client code, sorry for the
noise.
