in thread global variable initialization inside try{}

I just read this Re: Re2: Learning how to use the Error module by example
where it was told that the below code will leak memory

use Error qw( :try );

sub leaky_function {
    my $foo = 7;
    try {
        # do something here
        try {
            $foo++;
        } catch Error::Simple with {
            # whatever
        };
    } catch Error::Simple with {
        # whatever
    };
}

please explain me how it leaks memory when I call it every time.

In the bottom of that post it says that this leak was fixed in recent versions of perl. It used to leak by creating copies of $foo. If you're on a version prior to 5.8, you should still be concerned about it. The other problems with the try{} syntax still exist.
