I tend to use something like choice 1 to approximate this thing when I need it (and I tend to need it when I push functional class-based programming during "hell" projects). -- Matthias

Good point. I guess I'll deal for now.

Two ideas:

A syntax form that works with an interface (updateable<%>) that makes
the class deal with this stuff. (A related note syntax transformers in
the class system's interfaces might work analogous to the unit
system's)

A syntax form that is only legal inside the the class, so it can know
what all the fields are. (Although this would probably break for a
subclass's private fields.)

Ah, I asked this question recently only to be reminded of my age by my grad
students. How'd you copy private vars and methods?

Is there any way of making something like struct-copy for objects?

It seems like object-info and class-info have the machinery, but I'm
wondering if there's some fundamental reason it wouldn't work.

I'd like to use the object system functionally without writing lots of
boiler plate.
