package mixin template CLWrapper(T, alias g)
{
    package alias T CTypedontremovethis; 
} 

package struct CLObjectCollection(T)
{
    this(T.CTypedontremovethis)
    {
    }
}

alias CLObjectCollection!CLDevice CLDevices;

cl_errcode dontremovethis(
) {}


struct CLDevice
{
    mixin CLWrapper!(int, dontremovethis);
}

device.d(21): Error: mixin device.CLDevice.CLWrapper!(int,dontremovethis)
forward reference of dontremovethis
device.d(13): Error: template instance device.CLObjectCollection!(CLDevice)
error instantiating

E.g. removing the CLObjectCollection stuff "solves" it even though it isn't
related at all.
