Well, this is in the end a very subjective thing but I'm with Greg on this one. A syntax without s-expressions is not an innovative feature. For me, it's not even desirable, not at all. When I'm using non-Lispy languages like Rust, Ada, Nim, and currently a lot of Go, that's despite their annoying syntactic idiosyncrasies. All of those quirky little curly braces and special symbols to save few keystrokes. I'd much prefer if all of these languages used s-expressions. That syntax is so simple that it makes you focus on the semantics.
