// Module A does events

module.exports = function DoEventStuff(){
  /*
  
  Do DOM event things like A.on('event')
  
  Stores info about bindings in an array.
  
  */
}

// Module B needs events

module.exports = function(){
  var events = require('a');
  
  events.on('bla');
}

// Module C needs events

module.exports = function(){
  var events = require('a');
  
  events.on('bla');
}


Both module B and module C should be able to bind events, and these events need to know about each other.

Module C does not know Module B exists

The top level module that requires B and C, does not know about module A, nor does it need to, and as such, I'd rather not require('a') just so it can pass it to both B and C.
