I like using subshells for this:

  (
      cd dir
      for f in ./*; [..]
  )

There's a few scenarios where this won't work (mainly if you want to set a variable from the "outer scope"), but 99% of the time it works nicely.

Ah, that's a nice/neat thought - thank you for sharing! Makes total sense, temporary/disposable shell for such things
