As for me, I don't like ubiquitous $ everywhere, often I prefer parentheses
over $ (this might be due to my Elisp practices), and I like very much dot

Most uses of "$" are for stupid
things like "sin $ 1 + 2" where parentheses would be much more clear.


"$" simplifies visual perception through two factors:

I think this does not hold for every single person.

   1. we are relieved from counting parentheses

This is not big deal if your editor/IDE can highlight parentheses and even
better provide commands to jump to opening/closing parenthesis.

foo (thInt $ fromIntegral $ c2hsValueInt cexp) (thInt $ fromIntegral $
c2hsValueInt cexp)

foo (thInt (fromIntegral (c2hsValueInt cexp))) (thInt (fromIntegral
(c2hsValueInt cexp)))

Me, I get a blood pressure spike roughy here ---^

Personally, I find hard to read expressions like:

someFn $ someOtherFn $ more $ more $ val

(someFn . someOtherFn . more . more $ val)

seems better for me, but this is also good:

someFn (someOtherFn (more (more val)))

Parentheses annoys me only when I need to wrap something by parentheses in
