Would it be something similar to with in VB or Javascript? While we have that idea in for-aliasing, it certainly would be nice to have that concept a little more elaborated. I could see the benefit as such: 
# $object1 has the interface foo
# $object2 has the interface bar and baz
with ($object1)
{
    with ($object2)
    {
        bar;
        foo(baz);
    }
}

and have it be interpreted as: 
$object2->bar;
$object1->foo($object2->baz);

Obviously, this is a contrived example, but it could be kinda neat ...

      But the inner given would hide the topic of the outer given. There's only one $_ variable...

      Also, Perl 6 does not intuit that foo() should be a method call just because you happen to be in the scope of a class that defines method foo(). (That's a thing I hate about C++, actually.) So if you want to call a method without specifying the object, you have to at least put in the dot: 

           .foo()      # same as $_.foo()

      If you find yourself wanting to nest interface contexts, it's probably a sign that you should have designed the class with both interfaces in the first place. A class is the natural gathering point of interfaces (or roles, in terms of Perl 6's generalization of interfaces).
