Good point. I did a quick scan of the source code and came up with a
list of possible candidates for a similar treatment:

array_map()
array_diff() & friends
array_intersect() & friends
compact()

While I would not expect these functions to be used a lot with spread
operators in the same way array_push() or array_merge() are used, fixing
them in the same way may still be good for the sake of consistency.

Any other functions I overlooked?
