Proof-of-concept for an AMD (Asynchronous module pattern) written in CoffeeScript, inspired by the way how ImpactJS handles modules

gistfile1.coffee

do (window = @) ->
  cache = {}

  window.module = (name) ->
    deps = []

    requires = (dependencies) -> 
      deps = if Array.isArray dependencies then dependencies else [dependencies]

      {requires, defines}

    defines = (functionBody, context = @) -> 
      callArray = []
      for d in deps
        callArray.push cache[d] if cache[d]

      cache[name] = functionBody.apply(context, callArray)

      {requires, defines}
