Can we have subclasses of Process?

Hi.

Is it allowed to subclass Process? I remember that there were some problems with it but I could not find any information.

Generally I think about system processes which can be represented by concrete subclasses. For example explicit UIProcess can be used to remove many #isUIProcess conditions from system.

Best regards,

Denis

I've used subclasses of process for the debugger stuff without problems.

I think there is no technical limitation for it, AFAIK, the VM never checks the class of a process. I also proposed something like that in this paper:

EventualProcess is in eventual_test [*], as example. Do not run RefsTest>>#testFailedArithmaticwithEventualArgument or will segfault vm.
