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

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...

🤷‍♂️
