[Israel.pm] reference to tied variables

Please consider the following code segment:
tie my $Foo, Momo;
$Bar = \$Foo;
$$Bar = 4;
print $$Bar, "\n";
Surprisingly, this actually works (ie, whatever magic Momo introduces
applies in the assignment and printing). My question is first whether it
is intentional, and if so, how do I untie whatever is tied now, and when
the controlling object gets destroyed.
The reason I ask is that I managed to apply this nicely by combining it
with overloading, and all works fine until I get to the destruction of
the controlling object, where I see very weird things that I can only
describe as a bug.
I love deadlines. I like the whooshing sound they make as they fly by.
