Both cases are different in your example above. Top level elements are
labeled "An instance ...", whereas "inner" instances are labeled
"Instance of ...".

There's only one way this can happen: by falling through to the last
case of build(). Check the regexps etc. again.

Your last "Instance of..." case is correct, but "An instance..." is
different, because there's no containing object, so it's probably more
like: return Stanza(couple[1]).
