Rose::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.

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.

error [ERROR]

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.
