I would argue "type declaration" is wrong as well since it is not a type declaration as it is known in other languages where the type declaration is binding. IMO it is more a "type check". Consider the following function foo(Bar $b){ $b = 1; //$b is not a Bar at all }

I tend to think of them as "type assertions", since this: function foo(Bar $b){

    // do stuff

} is kind of equivalent to this: function foo($b){

    assert($b instanceOf Bar);
    // do stuff

} i.e. it's a runtime-enforced check
