"Everything is an expression" is pretty different. You can say ML/Lisp, but those are non-top-10 languages/styles.

No, in Ruby, everything is also an expression; this is sometimes unrecognized because some constructs that are cognates to constructs that are statements in other languages are frequently (but inaccurately) referred to as statements in Ruby (the most frequent example I've seen is "case statements").

Eh you got me. I still think it's pretty surprising (especially for systems languages), but OK :)

Also Ruby is a kitchen sink language, so I don't know if we should be using it as the baseline for a language with a small surface area.
