Attribute::Abstract - An Abstract attribute
use Attribute::Abstract;
package MyObj;
sub new { ... }
sub somesub: Abstract;
package MyObj::Better;
use base 'MyObj';
sub somesub { return "I'm implemented!" }
This attribute declares 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.
None known so far. If you find any bugs or oddities, please do inform the author.
