I'm using shells and enter to manage a "dirstack". I want to "popd" to remove dirs I've added.
I also have some aliases that I no longer want in my session. How do I delete the aliases?
I've tried things like drop but if the dirs and aliases are possibly immutable, how do I change them (without starting a new session)? Feels like there should be commands like leave (or unenter vs enter) and unalias (vs alias).
