I'm trying to do this equivalent C++:

in D, but obviously with an associative array. It seems that it's quite
easy to iterate through the whole "map", but not start from the middle.
Am I missing something obvious (or not so obvious) ?

Something like the following perhaps, which sorts the keys:

import std; // Sorry :(

void main() {
    auto m = iota(20).map!(i => tuple(i, format!"value_%s"(i))).assocArray;

    foreach (key; m.keys.sort.find(13)) {
        writeln(m[key]);
    }
}
