Uh, what about lisp? The (MIT) lisp 1.4 manual (ca. 1965) refers to FUNCTION differing from QUOTE in that it handled free variables "correctly"; I take this to mean that at least a primitive form of closure was provided. Moreover, a language that provides SET/SETQ, RPLACA/RPLACD and the PROG feature (including labels and a goto) surely qualifies as imperative? -- Bill Wood _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
