Component/s: mongorestore
Forgetting that MongoDB doesn't allow periods in database names, I used the dot notation in an attempt to create a namespaced database during a recovery operation:
mongorestore -h recoveryhost --port 27018 -d myproj.recovered .\dump\myproj
connected to: recoveryhost:27018

As you can see, using the period in the name caused the cases to be restored to the recovered.cases collection on the myproj database.
As it turns out, this isn't a big deal, but it came as a surprise and could have been a big deal if 'recovered.cases' had already existed in the 'myproj' database.
I suggest mongorestore should reject a database name with a period in it.
