> Arie van Deursen argues that “code formatting is a security feature” and that indentation “white space is a security concern. The correct indentation immediately shows something fishy is going on...” [vanDeursen2014]. Arie van Deursen also argues that code formatting should be done by tools, not by hand, and shows that clearly this code was not routinely formatted automatically.

Praise then for languages with significant white space? Using a formatter tool to add the white space and a lint rule in your compiler to catch when it's not done is a bandaid for something that should be encoded into the language in my opinion. Leaving this stuff optional to enforce only eats up productivity for no decent upside.
