Thoughts?
Without considering the subtleties of the different meanings of "." in
Haskell, I fail to see what people find so exciting about left to right
function composition. I find "not . null" much easier to read than "null
>>> not", let alone ".null.not".
IMO, the following are good reasons for keeping the current
semantics/notation of ".":
- It's a conventional notation (, unlike for example >>>).
- It makes it easy to switch back and force between point-wise($) and
point-free(.) notation when appropriate. I do this a lot.
If I were to fix the language I would probably use something like ":" or
"::" for selection and keep "." for composition.
