 # Five lines of code that will make your underscore + CoffeeScript use cleaner.
 # Creates an underscore function for each function in to_reverse with R (short for Reversed) appended to the name.
 # The R version moves the function argument (first argument in normal underscore) to the end, 
 # so you can write:
 $(window).scroll _.throttleR 500, ->
    console.log "This print's at most every 500ms"

 # Instead of:
 $(window).scroll _.throttle ->
        console.log "This prints at most every 500ms too"
    ,
    500

 # The code (Add immediately after you include underscore.js):
 to_reverse = ['bind', 'delay', 'defer', 'throttle', 'debounce']
 mixin = {}
 for name in to_reverse then do (name) ->
    mixin["#{name}R"] = (args..., f) -> _(f)[name](args...)
