You could probaly make
use ClearCase::Version Module '@@/main/03';
"Do the right thing" i.e.
ClearCase::Version::import could mimic perl's lookup of where .pm file
is then append the suffix:
require "/some/path/Module.pm@@/main/03";
What is less likely to work though is finding associated things like
sub-modules or loadable .so files.
It is irritaing that looking in a versioned directory does not
"just work" and give you the versions of the files that were current
at the time.

But with abormal file names ;-)
