associative array definition

I suggest you to use the d.learn group for this kind of questions.
I think you can't define AAs statically, but you can do something like:

string[char] map;
static this() {
    map = ['a':"foo"[], 'b':"bar"];
}

the static this() is executed before the main().

----------------

Note for the other people, static AAs (and static sets, if D will ever have them) can enjoy perfect hashing, this is a recent note of mine:
