Can drag and drop behavior be implemented via scripts, or must you subclass Morph?

I see that making a dropOn script seems to hook into the drop handling. Can I call the dropOn method from the dropOn script? My naive attempt caused a stack overflow...

If you override dropOn, you need to use $super(evt) to call into the
original method.

A script is just an instance specific override. From: Sean P. DeNigris

Ahh, thank you. That did it:
this.addScript(function dropOn(morph) {
    alert('do this first');
    return $super(morph)
}).tag([]);
