Well, "use t::Foo" is reasonably common in test scripts, but more
importantly, this would break installation of any dist that uses
Module::Install (which works by "use inc::Module::Install"). CPAN
clients (and possibly test harnesses) would need to be updated to add
'.' back in during module installation in order to avoid breaking
a significant portion of CPAN.
