/**
 * A factory for creating a binding expression for an unscoped instance.
 *
 * Note that these binding expressions are for getting "direct" instances -- i.e. instances that
 * are created via constructors or modules (e.g. {@code new Foo()} or {@code
 * FooModule.provideFoo()}) as opposed to an instance created from calling a getter on a framework
 * type (e.g. {@code fooProvider.get()}). See {@link FrameworkInstanceRequestRepresentation} for
 * binding expressions that are created from framework types.
