Extremely slow curry #12

Bilby's curry compared to LiveScript's curry on same code. Image speaks more than words: Imgur

Any chance of knowing what you're testing (examples, test cases), so we're not comparing apples and oranges.

I'm testing with some simple lazy streams code. I made a jsPerf. Bilby is like 10 times slower.

While performance is important, they are for totally different things.

I see the difference, but I think that bind is trying to do too much, so curry becomes slow. Bilby uses curry in many places, this optimization would improve performance a lot. Why not create a partial function, and a bind function?
