`__ctor` doesn't create a new object, it initializes an

call `__ctor` on it:

}

Thank you! Do you know any other way to do it without using
"__ctor".
No, there is no way to pass template arguments to a constructor
without using `__ctor`.
My recommendation is to use a free function or a `static` method
instead. For example:
```d
import std.stdio;
struct Test {}
Test makeTest(string type = "def")(string reg_arg)
{
writeln("reg_arg: ", reg_arg);
return Test();
}
void main()
{
auto test = makeTest!"non_def"("Hello");
}
```
