One solution:


struct Foo {
     int foo;

     @disable this();

     this(int foo_) pure nothrow @safe @nogc {
         this.foo = foo_;
     }
}

struct Bar {
     enum arraySize = 3;

     Foo[arraySize] foo = Foo(1);
}

void main() @safe {
     import std.stdio;

     Bar bar;
     bar.writeln;
}
