I'm using enum to compute the value at runtime like this:

struct A
{
	enum foo = A("foo", 10);
	enum baa = A("baa", 20);

	string name;
	int value;
	alias value this;
}

In order to avoid foo having its value (even if literal) copied every time A instancied and duplicates, shall I use static here?

I'm assuing that it works like this:

int f() {
   int a = 30;
   int b = 50;
}

and static would make it like this:

int f() {
  static int a = 20;
  static int b = 30;
}

int are examples, of course. I have A and array of A in my code.

No, enums are not part of the instance, they are part of the type. foo and baa will only exist when used.

static would also work, but is not necessarily usable at compile time.
