+ * A proxied implementation of AccountInterface.

+ * The reason why we need an account proxy is that we don't want to have global
+ * state directly stored in the container.
+ *
+ * This proxy object avoids multiple invocations of the authentication manager
+ * which can happen if the current user is accessed in constructors. It also
+ * allows legacy code to change the current user where the user cannot be
+ * directly injected into dependent code.
