I have always considered it a weakness that VectorSpace did not use CardinalNumber for dimension -- even if for all practical purposes NonNegativeInteger is sufficient and more efficient. That, in my opinion, calls for an efficient abstraction, e.g. find a way to support CardinalNumber and make the common cases as efficient as NonNegativeInteger. (please don't mention `subsumption', I don't want to go there.) -- Gaby ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
