variable's value in the previous state

I was wondering if there is a ready function to get the value of a variable in the previous state? Or just a prefix (e.g. 'pre') or somewhat like 'now'?

Re: variable's value in the previous state

there's no predefined function to do so -- you can of course add
a ghost variable yourself, to remember the previous value...

atomic { a_prime = a; a = newvalue };
