I think it makes much more sense to deprecate all of them and introduce

`end()` and `reset()` would have to continue working as they do until
the next major release since people who use them might rely on the way
they work. This means in effect that nobody can make her PHP 7 code PHP
8 ready up front.
Instead we could directly introduce `array_first()` and `array_last()`
with the next feature release -- even if the others are not deprecated
-- and everyone can update their code or at least use it in new code.
I've always felt like these functions were "missing" from the language -
there are a number of ways you *can* get the first or last item in an
array, but all have side effects, because they're not designed for this
purpose. It just so happens that - most of the time - reset() and end()
have the smallest side effects.
I can't remember if it was an earlier discussion here, or somewhere
else, that pointed to getting the first and last *key* as an extra use
case worth considering. It's currently possible (if awkward) with key().
I think it would make sense to, in the same version:
- deprecate reset(), end(), each(), and key()
- introduce array_first(), array_last(), array_first_key() and
array_last_key()
- document replacements for whatever other use cases we can find examples of
Doing them all at once makes the messaging much clearer - this family of
functions is going to be removed; and here are the new functions you can
start using immediately instead.
