As I said, this is considered sloppy programming, and both in Java and 
in Python ("from xxx import *"), this practice is highly discouraged. 
This is because you bind modules together more than necessary.
If you need in module A name B.b and deprecate B.b later, then there is 
no reason to have imported everything from B.
In Java, the IDE does the work of importing the exact packages/classes 
needed for you, but in Python, you have to do it by hand. It seems that 
it would be just as bad in D as in Python since compilation errors don't 
appear until templates are instantiated.
