Class::Homonymous_Union - a union of homonymous packages making up a class

Imagine three developers want to work on the same package, but as
different files. So that everybody edits a file called Synopsis.pm,
although from different directories. As the package file name is
always the same, they can't simply set up inheritance to form a
union. Unless they use Class::Homonymous_Union, which enables
inheritance from homonymous packages.


The output 'cover -test' with a modified t/03_hardly_reachable.t, so
that the error does not happen in the external script, but is checked
manually outside:

----------------------------------- ------ ------ ------ ------ ------ ------
File                                  stmt   bran   cond    sub   time  total
----------------------------------- ------ ------ ------ ------ ------ ------
blib/lib/Class/Homonymous_Union.pm   100.0  100.0    n/a  100.0  100.0  100.0
Total                                100.0  100.0    n/a  100.0  100.0  100.0
----------------------------------- ------ ------ ------ ------ ------ ------

The 100% coverage are relative to what can be tested. The particular
spot where additional code is added if $^S isn't set refers to a fatal
failure. While it is tested in the unmodified t/03_hardly_reachable.t
through an external script, Devel::Cover won't see that. Therefore the
manual check with a modified version.
