programStations is an Ember.ArrayController

  console.log programStations.mapProperty('id')
  programStations.forEach (programStation, index) ->
    console.log "#{index}: #{programStation.get 'id'}

outputs:

-Ivme_qDpo-jLuDoDKWb,-Ivmeanfr5UpajT0w2ro,-IvmecErq7nPccMraauU,-IvmecF1BtqNxqXMc4qC,-Ivmfr2igN9vHLwkIGQT,-IvmehN0Guvy2j_-VA4J
0: -Ivme_qDpo-jLuDoDKWb
1: -Ivmeanfr5UpajT0w2ro
2: -IvmecErq7nPccMraauU
3: -IvmecF1BtqNxqXMc4qC
4: -Ivmfr2igN9vHLwkIGQT
5: -Ivmfr2igN9vHLwkIGQT

Compare the last item in the array vs the last thing logged in the forEach iteration. wtf :/

(Still haven't managed to get this down to a simple jsbin reduction.)
