HELLO-FELLOW-GUILERS

I wrote some threading macros ages ago that I never properly released. They are clojure-like threading macros but with cut-like placeholders. 

A simple example would be ~> (left insert, when no <> placeholder is found):

(~> (list "hello" "fellow" "guilers") (map string-upcase <>) (string-join "-")) => "HELLO-FELLOW-GUILERS".

Other forms are also provided:

and~> stops when any intermediate value is #f

lambda~> threading lambda (lambda~> ...) is the same as (lambda (id) (~> id ...))

define~> (define~> id ...) is the same as (define id (lambda~> ...))
