This is pretty cool. Thanks for sharing.

I have a few questions/comments:

1) It might make a good blog post at some point to discuss this 
and the performance (perhaps with reference to the earlier open 
methods blog post).
2) It looks like Polymorphic can only take one interface. Would 
you consider adding the ability to have more than one? I suppose 
a work-around would be to combine all the interfaces you would 
want to use into a new interface before combining.
3) Do arrays work, as in Transformer(Adder(2), Plus1()) or 
[Transformer(Adder(2)), Transformer(Plus1())]
