But it’s not `a b c`. Rather it’s something like `verb noun noun`. Which is much less ambiguous.
In a language with currying semantics [(((a(b))(c))(d)] the only logical explicit syntax sugar would be LISP-like, so (v n n), (v (v2 n)). That’s imo way worse — you end up with lots of useless junk)))))))) in anything non-trivial.
