I found @DougChasman using
in his example here How to set up views and navigation in Lightning?
However in the docs I see only
$A.newCmpAsync and marked DEPRECATED.
Is that example referenced above no longer working in it's exact form?
Only in case it's no longer working: since there are only rare examples of that kind, wouldn't it be worth for us as community to update it to be compatible with the current release and today's best practices?
