On the Plugins page of the documentation, the following example is presented:

plugins: [
  // Karma will require() these plugins
  'karma-jasmine',
  'karma-chrome-launcher'

  // inlined plugins
  {'framework:xyz', ['factory', factoryFn]},
  require('./plugin-required-from-config')
]

Although I haven't needed to write my own inline plugins yet, I doubt the example provided is correct, since it's not even valid JavaScript syntax. Should it be { 'framework:xyz' : [ 'factory', factoryFn ] } instead? A little explanation on that point would be appreciated.
