This code can contain more than one problem. This is a reduced test case that
shows one of the problems:


class A(T) {}
class B(T) {}
alias B!Foo Bar;
alias A!(int) Foo;
void main() {}


dmd 2.043 shows:
test.d(3): Error: forward reference to 'A!(int)'

So a alternative way to solve this problem is re-typedef the it


class A(T) {}
class B(T) {}
alias B!Foo Bar;
typedef A!(int) Foo;
void main() {}

but this will cause a new problem,see below

class A
{
  static A create();
}
typedef A B;
unittest
{
   B b=B.create();//error: A can't convert to B
}

should A create() change to B create when typedef used?
