I don't disagree, I do find Ruby readable, and it was the first language that caught my eye back when I was a kid, precisely because of its readability and expressiveness.
I suppose we have to define expressiveness (conciseness, abstraction power, readability, flexibility?), because Ruby, for example, has human-readable expressiveness, Common Lisp has programmable expressiveness, and Forth has low-level expressiveness, so they all have some form of expressiveness.
I think Ruby, Crystal, Rebol 3, and even Nim and Lua have a similar form or type of expressiveness.
