Hi,
        I recently tried writing some code to simulate a certain protocol in 
Python. 
I thought I'll go the "smart" way and rely on the Python yield construct to 
do a CPS transformation of my code.
        While this worked to a certain extent, composability was a problem, 
because 
any sub-procedure which used yield (and thus was an iterator) required being 
called in a rather inelegant way.

Thanks!
