I'd just like to mention that the Option type comes from FP and it's not necessarily needed in PHP-land where we have flow-sensitive type checkers like Psalm (a nullable type ?int or such is refined to just int after a null check). Flow-sensitive type-checking was not invented when the Option type was first created, so adding it to PHP is basically stepping back in time, from my point of view. Olle
