System Information
Win 10, GTX 970

Blender Version
Broken: 2.8

Short description of error
A collection can contain itself. It's actually pretty neat and I guess you can do cool stuff with that - though having a slider or something like that to limit the amount of recursions would be cool.

Exact steps for others to reproduce the error
Create a collection, instance it, move that instance into the original collection

Attached
A screenshot
A demo blend file
recursivecollections.blend

@brecht I thought we had checks to prevent that kind of recursion?

This behavior is still present in current builds and can result in pretty nasty bugs and performance related crashes. Assigning @dfelinto upon his twitter comment .

You can get interesting results with these recursive collections.
I just wonder why it's not infinite.

I wasn't able to parent collections recursively in the outliner or the properties editor, so I'm assuming this is resolved. Maybe I'm misunderstanding how this worked though? If I'm wrong please comment here.
