I'm on FuelPHP 1.6 dev and has been installing packages through composer. I'm thinking, is there a FuelPHP social package (or just Facebook for now) that used composer?
I remember you mentioned before in my Monga composer question that I need to create a static class to handle this? I assume that's going to be the same approach?
A static interface, with forge() and instance() methods is handy if you need to pass objects around a lot. Instead of doing that, your static class can act as a container for your objects, and you can use the instance() method to access them from anywhere.
If you don't have that requirement, and only need the object within the scope of a controller or controller method, use normal instantiation, and either use a local variable or a property.
