 `withr::defer()` can be used as a drop-in replacement for `on.exit()`, but the real reason to use it is to get its default "stack-like" behaviour and to use its `envir` argument (in more advanced usage).
 
 The general pattern is to capture the original state, schedule its eventual restoration "on exit", then make the state change.
