Well, it B*gg*rs up %MY::

The currently planned semantics are:

    {
        my $x;
        exists %MY::{'$x'}; # true;
    }

and

    {
        my $x;
        {
            exists %MY::{'$x'}; # false
        }
    }


so consider:

    {
        my $x;
        my $dup;
        my $dup;
        exists %MY::{'$x'}; # true?
    }

which invisibly becomes

    {
        my $x;
        my $dup;
        {
            my $dup;
            exists %MY::{'$x'}; # false?
        }
    }
