Not all that much: they both return a meaningful result.  We cheated a
little bit by allowing the recv functions to modify the state of their
input argument, but they still deliver a valid result object.

Then the send function would return void, which is surely not more
natural.  Also, there would be a much larger disparity between the
behaviors of the text and binary output paths.

Anyway it's about three years too late to be debating this ;-)
