SYNOPSIS
    Using the "tie()" interface:

      use ex::constant::vars;
      tie my $pi,     'ex::constant::vars', 4 * atan2( 1, 1 );
      tie my @family, 'ex::constant::vars', qw( John Jane );
      tie my %age,    'ex::constant::vars', John => 27,
                                            Jane => 'Back off!';

    Using the "const()" function:

      use ex::constant::vars 'const';
      const SCALAR my $pi,     4 * atan2( 1, 1 );
      const ARRAY  my @family, qw( John Jane );
      const HASH   my %age,    John => 27, Jane => 'Back off!';

    Using "import()" for compile time creation:

      use ex::constant::vars (
        '$pi'     => 4 * atan2( 1, 1 ),
        '@family' => [ qw( John Jane ) ],
        '%age'    => { John => 27, Jane => 'Back off!' },
      );
