Now we're getting somewhere. Simplicity is a good thing, even if holy
wars aren't.

My main concern with immutability is that it's a specific hack to
provide a join point for AOP-style management of state. It feels like
there's a more general mechanism that we're missing. Maybe it would be
useful to have an instance-variable equivalent of ObjectsAsMethods,
whatever that might mean. A MOP, maybe? Macros?

OTOH, a more general solution starts to become a PL research project
pretty quickly, and would probably never happen.
