A better fitting solution wouldn't focus on classic
MMD, but simply Dispatch, where type- and value-based
dispatching are two of many kinds of dispatching supported.
I've always liked the sound of Linda's tuple spaces
and view that as a nice generalized dispatch approach.
Procedure calls are

The usual list context / scalar context distinction would of course still be possible.
It's just about _extending_ context sensivity.
