    beforeAll = reducify(before)

before('abc', 'c') // 'ab'

add(1, 2) // 3
sum(1, 2, 3, 4) // 10

Absolutely. I suggest writing it using the liberated version of Array.prototype.slice ;-)

Let me know if you want me to add it -- else I'll wait for your pull request.

Nice :-)

p.s.: you should pull, by the way. Your name's on the readme file now.
