Hello internals,
I've changed the status of the currently introduced RFC to add the

What is the behaviour if the array does not exist? From the current RFC
it appears it would return null? Wouldn't it be better to return false
for this situation?
I don't like throwing false when something doesn't exist.
apcu does that - returns false instead of null when a record doesn't
exist, and it is very problematic when the stored value literally is false.
granted a boolean can't be used for an array key, but still, if there
isn't something to return than null is better than a boolean.
boolean is a value, null is the absence of a value, which is more
accurate, no?
