For compiling collections, yes.

Yes, because those can't change during compilation.

Sent it an "as:" to change its shape:
#(2 3 5 7) as: Set

{ #dog -> 'bark' . #cat -> 'meow' } as: Dictionary
Browse the Collection hierarchies from time to time. Lots of good stuff in
there. In your case, look at the "converting" protocols, and implementors
of #newFrom: (which #as: uses).
