But all of the above are extra steps you have to take and are not 
really Python anymore. You depend on 3rd party software to tune 
your code. With D I have full control over my code from the 
start. Cython and the like can introduce their own little 
problems. Another layer of complexity. Another black box.

If you have a nice algorithm that really improves the program and 
then you hear "Well, it takes about 4-10 seconds, it's written in 
Python", then you go "Arrgghhh!" Cython can help to speed things 
up, but you have little control over what is going on. So why not 
craft your own custom code in C or D whenever possible?
