Which tools do you miss in D?

This is a recurring event in the Python world: Java/C++ 
programmers that try Python, find it much more productive and 
nice, and fall in love with it, and then can't use it because at 
work they are forced to use Java/C++ (or sometimes because Python 
is too much slow for their purposes). Sometimes the end result is 
that they are less happy than before in doing their daily work. 
So sometimes they end not suggesting Python to their colleagues 
to avoid them the same sad realization. I remember hearing 
something similar in Haskell community too, that is spoils you 
too much.
