[Israel.pm] reference to tied variables

[Moshe Kaminsky]

Hi,

Please consider the following code segment:

====8<=====
{
    tie my $Foo, Momo;
    $Bar = \$Foo;
}
$$Bar = 4;
print $$Bar, "\n";
====>8=====

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.

Thanks,
Moshe
