This is my point. If using new breaks Guice, then what's the point of
Guice.
If I need to pass an Injector around to create classes, why don't I
just pass in the dependencies when I use the new constructor? I can
just replace the Injector with a class that holds references to my
dependencies. I would create this class at main just like configuring
a module.
If I did that, what's the point of Guice?
