Fair enough. If you're binding directly to a result, you can avoid the
subscripting by using sequence unpacking, which might look nicer:
(a,) = take(1, iterable, default)
or write your own one-liner helper :-)
I'm thinking that, given Raymond's long reluctance to add additional
functions to itertools, it might be easier to add `take` since it is a
strictly more powerful function than `first`. If we can only get one,
I'd go for `take` since it can do everything `first` would do and more.
