Just a quick question - if the views are set to be deprecated, what would be the way to do a (long) series of collection transformation without spawning multiple intermediate collections? So, essentially, equivalent of .view, transformations, .force?

You use an iterator, which has its own caveats, or you simply accept that chaining collection transformations is going to be ridiculously inefficient.
