New Comment:
I really prefer to be explicit about what you bring into a restricted scope.
That
has been PHP's approach from day 1 with the explicit nature of the 'global'
keyword to declare explicitly which global variables a function will muck with.
And in PHP 5.4 with the implicit binding of $this I think most of the
motivation
for a request like this is gone anyway.

Further examples exhibiting scope inheritance:
class Test{
public $func;
public function callFunc(){
$this->func();
}
}
$foo = 'hello';
$test = new Test;
$test->func = function() use implicit{
echo $foo;
}
$test->callFunc(); // hello

Description:
------------
Feature request for 'use implicit', or semantically similar syntax. Anonymous
functions with the use implicit directive inherit all variables from parent
scope in which they are declared, not called;
$foo = 'hello';
call_user_func(function() use implicit{
echo $foo; // hello
});
