This is a bit of a horrible implementation but it's less duplication in use and minification safe:


Em.superAuto = (keys..., func) ->
  str = func.toString()
  regex = /function\s*\(\s*\)/
  arrayRegex = /\@|\[\]/
  unless str.match(regex)
    throw "It doesn't look like you passed a function with no arguments"
  argNames = for key in keys
    splitKey = key.split arrayRegex
    splitKey[0].camelize()
  str = str.replace(regex, "function(#{argNames.join(', ')})")
  eval("funcWithArgs = #{str}")
  Em.computed keys..., ->
    args = for key in keys
      @get key.split(arrayRegex)[0] 
    funcWithArgs(args...)
