I see comments about enums being somehow implemented as tuples,
and comments about tuples somehow being implemented as structs,
but I couldn't find examples of static initialization of arrays
of either.
Finally after playing around with it for a while, it appears this
example below works for static array of struct initialization.
It also doesn't display the enum bug of hearts2 coming back as
hearts in the iteration.
I tried C static array of struct initialization syntax, and it
didn't work, which kind of surprises me.
module main;
import std.stdio;
void main()
{
struct Suit {string nm; int val;};
static Suit[5] suits = [
Suit("spades",1),
Suit("hearts",4),
Suit("hearts2",4),
Suit("diamonds",10),
Suit("clubs",11)
];
foreach (member; suits)
{
writefln("%s: %d", member.nm, member.val);
}
}
D:\dprojects\ConsoleApp1\ConsoleApp1>dmd -run main.d
spades: 1
hearts: 4
hearts2: 4
diamonds: 10
clubs: 11
