If all you want is to pass yielded values outwards, it's
not all that bad, although it could get a bit tedious
if you're doing it a lot.

However, if you want values passed back in by send() to
go to the right places, it's *considerably* more
complicated.

The expansion I posted just before shows, I think, that
this is not something you want to have to write out
longhand every time -- at least not if you want a good
chance of getting it right!
