Why do Commands return a result instead of Send() being void? #21

I had always thought the "right way" to do commands was to following CQS and therefore any command should be void (and be assumed to successful or it throws an exception)., but ShortBus doesn't do it that way.

I'd be interested to hear the reasoning for having Commands return results.

Check out the linked PR and also #15

Sometimes commands return a result. In HTTP after a POST the server should return a 201 with a Location header indicating the URI.
