Rose::Class - A very simple class base class.
package MyClass; use Rose::Class; our @ISA = qw(Rose::Class); sub foo { ... } ... MyClass->foo(...) or die MyClass->error; ...
Rose::Class is a generic base class for classes. It provides a single class method (error), but may be expanded further in the future.
error
A class that inherits from Rose::Class is not expected to allow objects of that class to be instantiated, since the namespace for class and object methods is shared. For example, it is common for Rose::Object-derived classes to have error methods, but this would conflict with the Rose::Class method of the same name.
Get or set the class-wide error. By convention, this should be a scalar that stringifies to an error message. A simple scalar containing a string is the most commonly used value.
