Deprecate delegates

There's a critical difference, is that the package:collection classes don't allow you to change the wrapped instance after construction. IMO, this eliminates several useful use cases where you need the wrapping for indirection.

This is where I scream for 'protection'. Having the wrapped item exposed bothers me.

Although, in the case where it's exposed as the base type (List, Map, etc) maybe it doesn't matter.

Yes, unless someone knows that the collection is a Delegating* they won't see the property for the wrapped item. If you really want protected you can always play tricks with passing a closure in the constructor, but that starts to sound convoluted.

Got it. I'll close. Colliding names is a bit annoying...but not worth pushing now.
