           Summary: Rebindable does not work with forward declarations
           Product: D
           Version: 2.036
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: michel.fortin michelf.com

import std.typecons;

class A {
    Rebindable!(const B) r;
}

class B {
    Rebindable!(const A) r;
}

Changing the template condition of Rebindable to use is(T == class) instead of 
is(T : Object) fixes things.

You forgot to post the error messages.

Moreover, are you sure this is a Phobos bug and not a compiler bug?

This one got fixed due to some forward referencing bugs getting fixed on the
last release.
