We've decider to add a new function not to break backward compatibility. 
Thus there's still receive fucntion working as it used to as well as 
receive2 function that works the way you've designed it.

In addition we've provided python help for the function (lines 219-225) 
and added you to the AUTHORS file.

Btw, before receive2 is stabilised, you may consider enhancing it by an 
option to do non-blocking message reception. All you have to do is to 
call C++ receive with 'block' parameter set to false and return (0, 
empty-message) pair in case no message was received.
