Very nice.  It's not clear from the text, btw, if normal exceptions can be 
passed into __next__, and if so, whether they can include a traceback.  If 
they *can*, then generators can also be considered co-routines now, in 
which case it might make sense to call blocks "coroutine blocks", because 
they're basically a way to interleave a block of code with the execution of 
a specified coroutine.
