It requires knowledge of the innards of the structure.  It is not quite that
same type of intrusiveness as modifying the definition of a class and thereby
causing significant rebuilds, etc..  Whether you have to add stuff inside or
outside the sequence structure itself is irrelevant in metaprogramming--because,
by definition, a different use of a metaprogramming construct requires a
rebuild.

Fair enough. :)
