E.g. an algorithm for signal processing. Python is fine for 
prototyping, but if you want your algorithms to work in a real 
world app at real time, you'll have to rewrite it in C/C++, D or 
whatever. I've adopted the policy (where ever applicable) to use 
D straight away. It's just not worth it to develop something in 
Python and rewrite it in D later. I don't see the benefits of 
writing in Python, only drawbacks in the long run.
