C++ allows you to put many classes in one namespace and also allows you
to have inner classes which are concepts analogous to putting more than
one tagged type in a package.  Java's definition of a package is
essentially a grouped collection of classes. Java also allows you to
have inner classes (I believe) and also allows you to define more than
one class within a given file, although only one will be publicly
available for use outside the file.

Note that it is recommended in Ada as a matter of good style NOT to put
more than one tagged type in a package.  (See Section9.6 of the Styl
Guide).  And I have to agree with this design choice.  When I do have to
put a seond tagged type in a package, I generally place it within the
context of an internal (child?) package.
