For one thing Mr. Virding needs them to implement his lua erlang language
thing :) We also could make great use of them in the standard libraries to
build efficient variants of maps:fold and friends.
I'm sure there are usecases that we have not seen yet that will come up.
I've learned over the years that people never use the API:s you create the
way to expect them to be used and always come up with the strangest and
cleverest ways of doing things.
