Error when using ember-concurrency

[clintongreen]

Expected Behavior

• I expected the addon to work with my app

Actual Behavior

• The app errors with this message:
• Error: Assertion Failed: @computed can only be used on accessors or fields, attempted to use it with numResultsTask but that was a method. Try converting it to a getter (e.g. get numResultsTask() {})
• I am not using @computed anywhere but the numResultsTask function using @task from ember-concurrency

Steps to Reproduce

• Install ember-concurrency ember install ember-concurrency
• Use @task for a function eg:
  @task({ maxConcurrency: 1, restartable: true }) *numResultsTask(searchContext) { // do something with searchContext }

I'm trying to run this in the same folder as my app. I'm not sure this is how its supposed to be used so please let me know.
