And therein lies the problem. That context switching comes with a cost. It's like trying to identify the eggs, chocolate chips, and flour once you've started mixing. You can do it (up to a point of course--recognizing this is where the analogy fails) but it's so much easier to do when they're not mixed together.

Perhaps your editor can help you see it (?)

That's just adding yet another tool which itself requires a certain amount of context switching.
