jQuery prependEvent em 5 linhas de coffeescript

Funciona em jQuery 1.9.

$.fn.prebind = (name, handler) ->
  @on name, handler
  @each ->
    handlers = $._data(@, 'events')[name.split('.')[0]]
    # move to the beginning
    handlers.splice 0, 0, handlers.pop()

Isso usa API interna ($ ._ data) e pode falhar nas versões futuras do jQuery
