I'm wondering if `sort` intentially does not accept a `key`
or if this is just a missing feature? (I suppose that if
the `order` argument is specified it would have to accept
a sequence of keys ...)
Thanks,

It would be very inefficient to call a key function on every element
compared during the sort. See np.argsort and

what is the preferred idiom for a descending sort?

I meant when you need to sort on a key (another vector).
Currently I'm just reversing

For float types you would need to use the negative.
Yes, that's all I could come up with.
So ... shd `sort` have a `reverse` option,
like Python's builtin?
