Currently I'm experimenting with it since classes are too bulky
for what I need, yet I really need some type of
behavior/dynamic polymorphism. So far I have a working model.
It takes the following limitations:
A question of efficiency comes up. If at compile-time we can
confirm only a couple branches/possibilities, then only those are
considered during run-time. During optimization is that code just
inlined to where it is called rather than the jump to opDispatch?
Seems like it should if it's small enough, especially if there's
only 1 possibility.
Now I guess a question out there for you all. Who would be
interested in an implementation and how would you use it? Does it
seem like a good idea? How many levels would you want to use?
One? Several levels allowing class-like inheritance?
