I’d argue that the BEAM needs a prolog-y language too — erlang is prolog-like in syntax only (lacking unification, backtracking, cuts, and other really fundamental constructions). This really screwed me up when I was first working with it — I expected functions to be reversible, expand unbound variables to the herbrand universe, etc.
