Code is poetry and even if you don't know the syntax or details of the tools of the language, a choice example up front gives you a sense of the "rhyme" and "meter" of the language.

Sure, some people are going to use that as an immediate gut filter for "doesn't look enough like languages I already know" or various pet peeves, but on the other side for those that love to dig deep into the syntaxes of esoteric/lesser-known languages it becomes like the first sniff when working on tasting notes of a beverage and tells you a lot up front to your "nose" faster than paragraphs of prose about the motivations of the language. "Ah, yes, I'm sensing a strong Python influence on top of earthy notes of Erlang and just a bit of floral Pascal-ness most recently from the vineyards of Typescript, perhaps?"
