that's very, very cool!

fortunately that's rather easy. b: copy [] append b to-set-word "foo" append b "bar" obj: make object! b probe obj make object! [ foo: "bar" ]

you'll probably prefer to construct objects like shown above, but ... prepare: func [ x ] [ r: make type? x length? x foreach [ k v ] x [ repend r [ to-set-word k v ] ] r ] make object! prepare ["x" 1 "y" 2 "z" 3] best regards, -- chris
