Possible workaround for lack of proper namespaces in js

gistfile1.js

function mixIn(module, target) {
  for (var name in module)
    target[name] = module[name]
} 
  
BASE = { 
  styled: function(x) { return '<b>' + x + '</b>' }
}

FOO = (function() {
  mixIn(BASE, this)
  return { 
    log: function(x) { console.log(styled(x)) }
  }
})()

// Test

with (FOO) {
  log('Hello world')
}

FOO.log('coolness')

try {
  log("this won't work") 
} catch(err) {
  console.log(err)
}
