BTW, I think the main reason why these are missing is that Cython 
development is largely driven by personal needs, and these features are 
rarely used in real-world Python code. Also, as a descendent of Pyrex, 
Cython was originally not intended to compile regular Python code, and most 
code that it compiles even today was written either for Pyrex or Cython 
specifically. That reduces the urge to get unimplemented language features 
done. I think generators are the most frequently requested one, though.
