IMHO, this bug should be closed as invalid, because the initial suggestion in
the bug report is completely wrong: it would drive you to put low-level stuff
in the root, and derived stuff in the leaves. Implementing that suggestion
would encourage poor design. 

The current behaviour of 'package' in D seems nearly identical to the one in
Java. Java has the same problem.

Here is a Java proposal to fix the problem, which was ultimately rejected.

http://jcp.org/en/jsr/detail?id=294

"Today designers are forced to declare elements of the program that are needed
by other subparts of the implementation as public - thereby making them
globally accessible, which is clearly suboptimal.
Alternately, the entire implementation can be placed in a single package. This
resolves the issue above, but is unwieldy, and exposes all internals of all
subparts to each other. "

I also found this link to be helpful:

I can't really escape the feeling that 'package' is a bit of a flawed concept.
The problems with it don't seem easy to fix.
