Ah, it looks like I was misreading "a turn" as "its turn", so I hadn't considered the forced movement perspective.Sure it was.
Quicken cast Cloud of Daggers next to the enemy. Push them in for damage. And then they take damage again at the start of their turn without being able to respond.
Now you cast it on them for damage, and have till the end of their turn to move out.
Note, allies can still push them out and back in.
I don't think this is clear in the 2014 RAW, but it does seem like the most elegant solution: a target takes damage at most to once per round, either at the start of the its turn or during its movement.Forced movement doesn’t trigger damage in 2014. The “enter the area” has to be part of the creature’s normal, voluntary movment
