The following module was proposed for inclusion in the Module List:
modid: Attribute::Abstract
DSLIP: RdpOp
description: implement abstract methods with attributes
userid: MARCEL (Marcel Grunauer)
chapterid: 2 (Perl_Core_Modules)

Attribute::Types Attribute::Memoize Attribute::TieClasses
rationale:
SYNOPSIS package SomeObj; use Attribute::Abstract;
sub new { ... } sub write : Abstract;
DESCRIPTION
Declaring a subroutine to be abstract using this attribute causes a
call to it to die with a suitable exception. Subclasses are expected
to implement the abstract method.
Using the attribute makes it visually distinctive that a method is
abstract, as opposed to declaring it without any attribute or method
body, or providing a method body that might make it look as though
it was implemented after all.
RELATED MODULES
Attribute::{Types,Memoize,TieClasses} also use attributes, but to
achieve different things. As such, they are related to the
implementation (and listed here only because Attribute::Handlers, on
which they all depend, is so new), but not in functionality.
