Compared to lisp? Ok fine. Syntax doesn't get more simple than Lisp. But compared to JavaScript? C++? C#? Haskell is top tier when it comes to syntactic and conceptual elegance. The biggest problem is tooling, I would say.
(I write Haskell professionally)
It's like declaring math statements, observations and rules as if it were a Math textbook.
"Haskell: more elegant than Javascript and C++" would make a good promotional motto.
That's like bragging how prettier you are than Danny Trejo.
