I wanted to know your opinions on this. For example : $key = "a"; $value = 1; $array = [$key => $value]; [$key => $value] = $array; We all agree that now $key = 'a' and $value = 1 And I wonder why What happens in this case : [$key => $value] = ['b'=>2]; $key = 'b' and $value = 2 or all is null ?

Do you have an opinion on object destructuring ? *Do you think seeing list() as the reciprocal of a function call is interesting ?* Otherwise, how to use a default value, type hinting, nullable/optional variable... It's not interesting ? There are many things that could be done with but don't work. For example : $array = [1, 2, 3]; [...$values] = [...$array]; My question is: I see list() as the reciprocal of an array(). Do you think it would be interesting for everyone if I proposed my vision?
