Tracking the dependencies of every decision made in the output from the
originating data and only restarting the "necessary" dataflow will
significantly slow done compilation.  Self-awareness is computationally
expensive.  A human will prefer working that way.  But even if you are
looking at a supermarket queue with barcode scanner cash registers,
typing in a number on the register for several identical items will only
cause speedups for significantly large numbers.  The brainless way of
doing everything mechanically without shortcuts tends to be rather
efficient.
