If you pass ESC_RAW as an escaping method and the value being requested is a non-scalar, instead of getting back the actual raw value you get the object decorated in such a way that values obtained from it are "raw".
There are certain things you can do to (for example) a raw array that you can't do to it's decorated counterpart so the current implementation could lead to unintuitive behaviour.
I don't think it's ideal for sfOutputEscaper to know about 'esc_raw', but I don't know there is any (pragmatic) way of doing this.
