Further, I believe we should show off D in all its virtue

at http://dlang.org/hash-map.html

by addition to

     int* p = ("hello" in aa);
     if (p !is null) {}

also include the even compacter

     if (auto p = "hello" in aa) {}

along with

     if (const p = "hello" in aa) {}

in the non-mutating case.
