So why not create a new instance each time you munge anything?

That's the approach I'd take. Each instance becomes a "result cache", with DESTROY performing cleanup where necessary.

This approach has a lot in common with functional programming: you're composing a result out of functions. The complication is that a side-effect of each function is a file-based cache that need to be managed.
