Specialized template in different module

[John via Digitalmars-d-learn]

If I define a template in one module, and specialize it in a 
second module, the compiler doesn't like it when I try to call a 
function using the template.

  module one;
  struct Test(T) {}

  void testing(T)(Test!T t) {}

  module two;

  struct Test(T : int) {}

  void main() {
    Test!int i;
    testing!int(i);
  }

Output:
  error : testing (Test!int t) is not callable using argument 
types (Test!int)

If I put everything in the same module it works. So are template 
specializations limited to the same module?
