&gt;Is your productivity dramatically increased by the choice of required separators? Of course not.<p>Yes, for me it does. A large amount of symbols on screen makes my mind drift away and it gets harder to concentrate on the flow and meaning of code. Semicolons or lisp parens are good examples of such visual noise. While productivity decrease is not drastic, it&#x27;s noticeable. The mind adjusts and this problem diminishes with time and practice of the particular syntax but it&#x27;s still present.
