Re: iterate over enum name:value pairs

Jay Norwood:

Using enums, despite their problems, if often better than strings.

    static Suits[] suits =  [
                {Suit.spades, 1, 6, SuitShort.spd},
                {Suit.hearts, 4, 10, SuitShort.hrt},
                {Suit.diamonds, 4, 10, SuitShort.dmd},
                {Suit.clubs, 10, 16, SuitShort.clb}
        ];

    foreach (immutable member;  suits)


In some cases you can also use with() to avoid struct/enum name 
repetitions (unfortunately it creates a scope, so if you define 
an immutable variable inside it, it will be invisible and 
destroyed once the with() scope ends. This reduces the usefulness 
of with()).


    with (Suit) with (SuitShort)
    {
        static Suits[] suits = [
            {spades,    1,  6, spd},
            {hearts,    4, 10, hrt},
            {diamonds,  4, 10, dmd},
            {clubs,    10, 16, clb}
        ];

        foreach (immutable member;  suits)
        ...
