They're similar, but there are differences. For instance, you can do
package(a) in D in order to do something like put the stuff in a.b.c in
package a rather than a.b. Also, package functions in D are never virtual,
which I expect is not the case for Java. The whole situation is also
complicated somewhat by the fact that D allows pretty much anything at
module-level, whereas as Java requires one class per module, though I'm not
sure that that has much direct effect on package itself other than the fact
that it's possible in D to mark stuff package that isn't in a class.
