There is no lack of tools if you can integrate well with existing 
ones like numpy, pandas, matplotlib, etc. I think a good role for 
D in such an ecosystem would be implementation of algorithms.

D's excellent template system can be leveraged to help it play 
well with dynamically typed languages. A D module to be called 
from Python may be kept in source form that is compiled and 
specialized on demand according to argument types and the dtypes 
and dimensions of numpy array arguments. Specific specializations 
will be cached so from the second call it will not incur the 1-2 
second overhead of compilation. If you only use the @safe subset 
there should be no danger in dynamically compiling bits of code 
and loading them into the address space of your session.
