=head1 NAME
Class::MakeMethods::Template::PackageVar - Static methods with global variables
=head1 SYNOPSIS
package MyObject;
use Class::MakeMethods::Template::PackageVar (
scalar => [ 'foo' ]
);
package main;
MyObject->foo('bar')
print MyObject->foo();
$MyObject::foo = 'bazillion';
print MyObject->foo();
=head1 DESCRIPTION
These meta-methods provide access to package (class global) variables.
These are essentially the same as the Static meta-methods, except
that they use a global variable in the declaring package to store
their values.
B<Common Parameters>: The following parameters are defined for PackageVar meta-methods.
=over 4
=item variable
The name of the variable to store the value in. Defaults to the same name as the method.

=head2 Standard Methods
The following methods from Generic should all be supported:
scalar
string
string_index (?)
number
boolean
bits (?)
array (*)
hash (*)
tiedhash (?)
hash_of_arrays (?)
object (?)
instance (?)
array_of_objects (?)
code (?)
code_or_scalar (?)
See L<Class::MakeMethods::Template::Generic> for the interfaces and behaviors of these method types.
The items marked with a * above are specifically defined in this package, whereas the others are formed automatically by the interaction of this package's generic settings with the code templates provided by the Generic superclass.
The items marked with a ? above have not been tested sufficiently; please inform the author if they do not function as you would expect.

=head2 PackageVar:vars
This rewrite rule converts package variable names into PackageVar methods of the equivalent data type.
Here's an example declaration:
package MyClass;
use Class::MakeMethods::Template::PackageVar (
vars => '$DEBUG %Index'
);
MyClass now has methods that get and set the contents of its $MyClass::DEBUG and %MyClass::Index package variables:
MyClass->DEBUG( 1 );
MyClass->Index( 'foo' => 'bar' );

my %rewrite = ( '$' => 0, '@' => 1, '%' => 2 );
while (@_) {
my $name = shift;
my $data = shift;
$data =~ s/\A(.)//;
push @{ $rewrite[ $rewrite{ $1 } ] }, { 'name'=>$name, 'variable'=>$data };

return @rewrite;
