An illustration of a condition where by "compute new benefit based on old" might be difficult can be one particular wherever the "values" are proficiently a references to a posh facts framework. Code may well fetch the outdated reference, derive a different knowledge framework through the previous, and after that update the reference. Atomic Wallet This pattern will come up a great deal more generally in garbage-collected frameworks than in "bare metallic" programming, but there are a selection of ways it can occur up even though programming bare metal.
