Perhaps future debates on this issue could be put to bed by using 
Pyrex.  Granted, Pyrex is not actually Python.  But it's awfully close, and 
would certainly address the issue of making algorithms clearer than would 
be the case in a pure C version.  (It also automatically produces 
subclassable types.)
