How about just using functions for everything? I'd really hate to have to
remember that if A is sparse, A.is<foo> works, but if it's dense I need to
instead use is<foo>(A).
Another alternative would be to suggest these modifications be made to
numarray proper, if the method approach appears preferable.
But I'd really like to vote for a _single_ syntax for property queries.
Ultimately which one doesn't matter that much to me, but I don't want to see
two different syntaxes for the same thing.
