I thought D was supposed to be a practical language for real world 
problems. This 'D is good because everything can and must be written in 
D' is beginning to sound like a religion. To me it seems the Python way 
is more practical in all ways. Even novice programmers can produce 
efficient programs with it by using a mixture of low level C/C++ libs and 
high level python scripts.

I agree that Python isn't as fast as D and it lacks type safety things 
and so on, but in the end of day the Python coder gets the job done while 
the D coder still fights with inline assembler, compiler bugs, porting 
the app, fighting the type system (mostly purity/constness issues). 
Python has more libs available, you need to write less code to implement 
the same functionality and it's all less troublesome because the lack of 
type annotations. So it's really understandable why a greater amount 
people favor Python.
