I'd say "languages with Algol-inspired syntax" rather than "traditional imperative languages". There's some overlap between the two, of course, but there are declarative languages with more Algol-style syntax (e.g., Prolog) and imperative languages without it (e.g., Smalltalk).

Also, does the adding parentheses make it anything other than legal (if ugly) Haskell? It looks to me like just anti-idiomatic Haskell where all the functions are defined to take tuples instead of being in the more idiomatic curried form?
