Any reason not to simplify this by losing the extra layer of indirection? 
package Tie::Static;
$VERSION = 0.01;

foreach my $type (qw(Hash Array Scalar)) {
  my $meth = uc($type);
  eval qq(
    package Tie::Static::$type;
    require Tie::$type;
    \@ISA = 'Tie::Std$type';
    
    sub Tie::Static::TIE$meth {
      my \$id = join "|", caller(), \@_;
      return \$preserved{\$id}
        ||= Tie::Static::$type->TIE$meth;
    }
    
  ) or die $@;
}

You should also mention in the POD that it's not a good idea to do this: 
tie (my $foo, 'Tie::Static'); tie (my $bar, 'Tie::Static');
# or this
map { tie $_, 'Tie::Static' } my ($foo, $bar, $baz, ...);
