           Summary: Template mixin with import + base class causes forward
                    reference
           Product: D
           Version: 1.045
          Platform: x86
        OS/Version: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody at puremagic.com
        ReportedBy: doob at me.com


The following code causes forward reference:

template Mixin ()
{
    import std.stdio; // it doesn't matter what import it is
    int i;
}

class Bar : Foo
{
    mixin Mixin;
}

class Foo
{
    mixin Mixin;
}

Flip the class declarations to get the code to compile. The problem is harder
to work around with the classes in individual modules.
