Trealla is not WAM-based. It uses tree-walking, structure-sharing and deep-binding. Source is byte-code compiled to an AST that is interpreted at runtime. The intent and continued aim of Trealla is to be a small, easily ported, Prolog core. The name Trealla comes from the Liaden Universe books by Lee & Miller (where it doesn't seem to mean anything) and also a reference to the Trealla region of Western Australia.
