Oh ok, you're referring to assignment as one expression, not the PLT definition of expression, which for that example would be like 3-6 expressions depending on whether you consider x, list, and 1 to be expressions. Yeah, a complicted formula might be more verbose in prolog because there's no return statements, it's all unification, but I think that's a feature not a bug, because it allows you to create bidirectional formulas and also naturally extends to "multiple return values" in a sense, because everything is a relation. |
