Right, I think I've worked out where the problem lies now.

Class::C3::Componentised's ensure_class_found() method *does not work* =

in the following situation: When the class exists inside a PAR file =

which is being accessed via the "use PAR 'archive.par';" method.

I attach the simplest test case I could create for this.

To demonstrate, try:
$ parl foobar.par test_c3.pl
Foo::Bar found.
$ ./test_c3_par.pl
Foo::Bar not found at ./test_c3_par.pl line 7.
