 If you're familiar with [immutability in Psalm](https://psalm.dev/articles/immutability-and-beyond) then this general idea should be familiar, since a pure function is one where the output is wholly dependent on its input. Unsurprisingly, all functions marked `@psalm-pure` _also_ specialize the taintedness of their output based on input:
