Besides it exposes a couple of things about aggregate() which are now

Weird, I'd have sworn it was there. Oh, well.
Second, in your usage above, "const" is
just a dummy that does nothing; one could replace it with "null". However,
one couldn't just omit it altogether, as in
ret = aggregate(,x) # error
but it seems that variant ought to be acceptable. It now is in git.
Ah, this is nice.
