           Summary: Can't deduce sizeof inner struct inside a template mixin
           Product: D
           Version: 2.020
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: 2korden gmail.com


The following code triggers an error:

template Foo()
{
    uint getSize()
    {
        return (*this).sizeof; // line 5
    }
}

void main()
{
    struct A1
    {
        mixin Foo!(); // line 13
    }
}

test.d(5): struct test.main.A1 no size yet for forward reference
test.d(13): mixin test.main.A1.Foo!() error instantiating

Reduced test case a bit:

mixin template A() {
    void foo() {}
}

void bar() {
    static struct C {
        mixin A!();
    };
}

     void foo() {}
 }
 
 void bar() {
     static struct C {
         mixin A!();
     };
 }


That works in 2.061, however OP code still doesn't work. Also it should
probably use 'typeof(this).sizeof', not '(*this).sizeof' (which gives a
separate error).

OP code is a dup of bug 9417.
