Frieldly optics name proposals

Here are some proposal for optics names. The goal is to give a better intuition to beginners, especially people with no FP experience.

Setter -> Replace, Modify, Write
Fold -> Aggregate
NonEmptyFold -> Reduce
Getter -> Read
ReadOnlyOptional -> ???
Traversal -> ???
NonEmptyTraversal -> ???
Optional -> Find
Prism -> Subset, Select, Branch
Lens -> Field, Focus
Iso -> Equivalent, Equivalence, Conversion

Prism -> Identify?

How about:

Fold -> Aggregate
NonEmptyFold -> Reduce

Should the optics be names or verbs? I guess we should be consistent (Reduce vs Reducer)

Personally I'd go for verbs, which to me sounds simpler and more natural for the majority of cases.
Yet I can see that, as alwasys, it depends on the term used... if you choose Focus... is that a noun or a verb? View? Update?
Project might cause misunderstanding wrt Projection...
