The following method uses a convenience function but it's not really needed:

import std.stdio;

struct TestArray(ulong element_n, string type) {
   int[element_n] elements;
   mixin(type) member;
   pragma(msg, "The type is: ", typeof(member));

   this(ulong number) {
     writeln("Constructing with ", number);

auto makeTestArray(ulong element_n, string type)(ulong number) {
   return TestArray!(element_n, type)(number);

void main() {
   auto ta = makeTestArray!(10, "int")(60);
