Summary: Forward reference with template mixin and derived
classes
Product: D
Version: D1 & D2
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: robert octarineparrot.com

The following source:
base.d
----
template Template(T:Base)
{
}
class Base
{
}
----
derived.d
----
import base;
mixin Template!(Derived);
class Derived : Base {}
----
Produces the errors:
----
derived.d(3): Error: class derived.Derived base class is forward referenced by
Base
derived.d(2): Error: mixin Template!(Derived) does not match template
declaration Template(T : Base
----
When compiled with dmd1 and 2, using `dmd base.d derived.d`. Moving the mixin
after the definition of Derived seems to fix the error.
