 * the binding logic ({@link Inject} constructors, {@link Provides} methods) upon each call to
 * {@link #get}.
 *
 * <p>Note that while subsequent calls to {@link #get} will create new instances for bindings such
 * as those created by {@link Inject} constructors, a new instance is not guaranteed by all
 * bindings. For example, {@link Provides} methods may be implemented in ways that return the same
 * instance for each call.
