Re^8: Informal Poll: Traits (Long Post Warning!)

[Corion]

When you have a generic proxy object like Object::Realize::Later, which more or less implements lazyness for method calls, it is quite convenient to have the object change class after it has been realized. Otherwise, lots of (brain-dead, I admit) checks fail when they ask UNIVERSAL::isa($obj,'foo');. Of course one could circumvent this problem with multiple inheritance or by writing a specialized ::Proxy class for every class to be lazy ...

Override isa() in your code and tell anyone who calls it as a function that their code breaks yours, 'cuz it does.

Class::LazyLoad doesn't need to do this. I wonder why you felt that Object::Realize::Later needed to do so.

[Corion]

From a look at the documentation, Class::LazyLoad doesn't seem to support classes that implement cheap operations but can become the full fledged object on demand. Which is what Object::Realize::Later does. There are ways around this that don't need reblessing into the full class I guess, like aggregation/creation of a new instance, but reblessing is the easy/safe way. This is discussed in the Traps section of the documentation.

This is true. C::LL supports non-existence or existence. Apparently, O::R::L supports the intermediate state. Neat!
