How would people feel about keeping REGISTER-IMMUTABLE-SYSTEM now (so as
not to break existing Genworks code), with it becoming deprecated later?
We would immediately put in IMMUTABLE-SYSTEM-P, as Attila suggests, as
a the permanent name?
If we are the only ones using it then you can also just go ahead and get rid of it right now. We don't have the code out in the wild, and can future-proof what goes out from now on.
