If I wanted to stir up controversy, I'd say that the ultimate 
cause of
this issue was the fact that struct fields can't be ref; 
otherwise it
would be a non-problem (make .key and .value ref, and then 
.tupleof will
Just Work(tm)).

struct S(Key, Value)
{
    private:
        Key*   _key;
        Value* _value;

    public:
        ref Key key()   @property { return *this._key; }
        ref Key value() @property { return *this._value; }
}

and no need for tuple weirdness.
