If that were the case, I'd want the compiler to scan *all* the key/value 
pairs for instances of derived types (rather than just being based on 
the first K/V pair, like is currently the case with other array literals).

For example (using tango classes, where HttpGet and HttpPost are both 
subclasses of HttpClient):

    // Type is: MyHashTableType!(string, HttpClient)
    auto hashtable = MyHashTableType [
       "get"  : new HttpGet(),
       "post" : new HttpPost()
    ];
