Bug description:type hinting with "self" keyword causes weird errors
Description:
------------
"self" should be thought as "the class where the keyword is written in".
Here is then a strange behavior using inheritance :
Test script:
---------------
class Foo {
public function setSelf(self $s) { }
}
class Bar extends Foo {
public function setSelf(self $s) { }
}
Expected result:
----------------
Strict Standards as Bar::setself() signature doesn't respect Foo::setSelf()
signature.
Foo's one has a type hint on Foo (using self keyword), but Bar's one on Bar
(still using self keyword) : the methods then have a signature mismatch,
and PHP
should complain about that
Actual result:
--------------
Nothing happens.
Trying this gives the correct E_STRICT error, correct behavior :
class Foo {
public function setSelf(Foo $s) { }
}
class Bar extends Foo {
public function setSelf(Bar $s) { }
}
