Thanks for the reply, chromatic.

i think i was perhaps not clear enough about my definition of 'class data', as opposed to 'class defaults', which i believe your response addresses. my apologies.

some typical 'class data' for example might be:

# base class
package AbstractMyClass;

my $_Class_Count = 0;

sub new
{
    my $class = shift;
    my $this = bless( {}, $class );

    ref($this) && $_Class_Count++;
    return $this;    
}

package MyClass;
@MyClass::ISA = ('AbstractMyClass');

sub new
{    
    my $class = shift;
    my $this = $class::SUPER->new( @_ );
    # this class' init...
    
    return $this;
}

if i were to use the code...

use AbstractMyClass;
use MyClass;

my $amc = new AbstractMyClass ();
my $mc = new MyClass ();

[download]

...$AbstractMyClass::_Class_Count would be 2, whereas i would have really liked $AbstractMyClass::_Class_Count to be 1, and $MyClass::_Class_Count to be 1. Probably a bad example of the essence of my original question, but nevertheless illustrative of what i am terming 'class data'. thanks, matt aka d_i_r_t_y, since 'zero cool' was taken... ;-)
