 New Comment:

Actually, thinking about it, it's not quite a bug. The function name is A\{closure} …
bound to the Class A\Foo. Hence we end up with A\Foo::A\{closure}.

In case you bindTo() another class, like the class Baz in namespace B, we'll have
B\Baz::A\{closure}, still indicating that the Closure is in namespace A.

Hence closing as not a bug.

This is a regression introduced by the bug fix for #70159 ... https://github.com/php/php-src/commit/a28115ccdb11301a418cc748ef7716a1687cc585#diff-3a8139128d4026ce0cb0c86beba4e6b9

Thus assigning to Julien.

Description:
------------
The namespace shouldn't be repeated after :: and -> for anonymous functions.

https://3v4l.org/F7R3l#v700alpha2

Test script:
---------------
<?php

namespace A {
    class Foo {
        public $foo;
        
        public function __construct() {
            $this->foo = function (int $a) {
                var_dump("foo");
            };
        }
    }
}

namespace {
    ((new A\Foo)->foo)(null);
}

Expected result:
----------------
Fatal error: Uncaught TypeError: Argument 1 passed to A\Foo::{closure}() must be of the type
integer, null given, called in /in/F7R3l on line 16 and defined in /in/F7R3l:8
Stack trace:
#0 /in/F7R3l(16): A\Foo->{closure}(NULL)
#1 {main}
  thrown in /in/F7R3l on line 8

Actual result:
--------------
Fatal error: Uncaught TypeError: Argument 1 passed to A\Foo::A\{closure}() must be of the type
integer, null given, called in /in/F7R3l on line 16 and defined in /in/F7R3l:8
Stack trace:
#0 /in/F7R3l(16): A\Foo->A\{closure}(NULL)
#1 {main}
  thrown in /in/F7R3l on line 8
