Implements generic aggregate support in the Sn registers. t/op/key.t has quick samples of its use. It does have fairly rigorous internal tests, but the memory allocation is rather primitive. It does do the job, but as nobody's come up with a memory gc scheme, it doesn't matter yet. -- Jeff <[EMAIL PROTECTED]>
