It should be an easy bit of programming; perhaps the hardest question is how to name these "functional setters", e.g. person-age-set set-person-age (without the !) person-with-age ..
What happened to (struct-copy person p [age 25])? Or are we talking only about student languages and this isn't in there yet?
