With some testing, I discovered that it's the act of explicit instantiation
that causes the line number to be tied to the declaration line:

ptrdiff_t Test1(string name, string file = __FILE__, ptrdiff_t line =
__LINE__)(){
    pragma(msg, line.stringof);
    return line ;
}

void main(){
    auto test1 = Test1!("test")();
}

prints 1.

This workaround does work:

Test2!(file, line) createTest2(string file = __FILE__, ptrdiff_t line =
__LINE__)()
{
   return new Test2!(file line);
}

I agree with the request that the line number and file should be tied to the
instantiation line, not the declaration line.
