Can a Library extend the CI_Base class?

Can I extend the CI_Base class in a library? Will this make my CI objects available in the $this-> variable?

Maybe my question was not clear?

I know how to extend the core classes. What I want to do is extend the CI_Base class with a class in my library folder.

Right now if you want to access variable in CI you have to use the =& get_instance() method... which is fine, just extra work. I'm wondering if i could extend CI_Base and access the CI variables with $this->db or $this->whatever. Is this legal?

You can extend any class, but you'll just be creating another instance of that class, you'll still have to use get_instance(), or assign all properties to the CI object to your new class manually.

I understand, and that makes a lot of sense. Thank you.
