This article (and your counter) feels to me like a higher abstraction level of the all too common code "readability" argument. The language isn't necessarily a puzzle language any more than this or that code-segment isn't less readable. It's all just more or less familiar to the reader. Language readability is MOSTLY on syntax or small bits of idioms and how expressions are put together. This article is just another level up from that.

"readability" is an aspect of the reader, not the code.
