With dmd from github, this causes an error (reduced by dustmite):

///////////
module aggr;
import type;

class Aggregate : Type
{
}

class Class {
}


///////////
module interpret;
import type;
import aggr;

class ReferenceValueT(T)
{
    void doCast()
    {
        auto x = Type.ConversionFlags.kAllowBaseClass;
    }
}

class ClassValue : ReferenceValueT!Class
{
}

//////////
module node;
import aggr;
template ForwardCtor()
{
}

//////////
module type;

import node;

class Type {

    mixin ForwardCtor!();


    enum ConversionFlags
    {
        kAllowBaseClass          = 0
    }
}

>dmd -c interpret.d
type.d(12): Error: enum type.Type.ConversionFlags is forward referenced when
loo
king for 'kAllowBaseClass'
interpret.d(9): Error: no property 'kAllowBaseClass' for type 'int'

This used to compile until a couple of days ago.
