Lens composition with (.) is not really a syntax choice - Lens composition with (.) is simply function composition with (.) which is a fairly deeply-set Haskell choice. I can see arguments against using (.) for function composition but I don’t think anyone would seriously consider changing that now: and Lens composition will always have the same syntax as function composition.

It just so happens that Lens composition with (.) gives us the ability to write person^.job.title which is one of those nice coincidences which looks a bit like C-style object dereference.
