Suspending and resuming a generator is quite an expensive operation.
send() has the triple whammy of method call + resume generator +
suspend generator, so it's unlikely to outperform a simple method call
(even one that redirects to another method).

Independent of performance though, I think the mutable sequence API
inspired append(), extend() and += are a better API for what you're
trying to achieve than "send", so it doesn't make sense to me to try
to shoehorn this into the generator API.

Cheers,
Nick.
