I side with the person who decided that wildcard imports were a good 
idea for the language. I think explicitly listing every single type used 
by a class as if it were a long list of C header includes is just wrong. 
I can see how some tools might find it useful, but for the programmer 
... yuck! If the IDE does it for you that helps but even then I don't 
want to see that list regardless.

Just my 2c as I run out the door on vacation :)
