One of the core ideas of Etoys was to have only a single "rich"
object type, not a hierarchy of classes. The embodiment of that idea
is class Player.
By current standards, that design is indeed "ugly". But we're stuck
with it at least for this generation of Etoys. The Tweak version of
Etoys solved that problem.
It helps if you think of the *player* as primary scripted object. You
are not scripting a Morph, it is only the costume for a Player, and
can therefore be exchanged.
