A (hopefully) simple question. How would you implement #perform:with:
? JS can handle the reflection (either via eval(...) or function
pointers).

BTW: This looks great!

"I am crucified with Christ: nevertheless I live;
yet not I, but Christ liveth in me: and the life
which I now live in the flesh I live by the faith of
the Son of God, who loved me, and gave
himself for me."
    Galatians 2:20
