Usually you create an object

my $logger = common::system::utilities::Logger->new;
$logger->print( ... );

or a subroutine  sub LOG { &common::system::utilities::Logger::print }

but you can do "aliases" with Package::Alias  use Package::Alias Logger => 'common::system::utilities::Logger' ;

or do it yourself

 BEGIN{
use common::system::utilities::Logger;
*Logger:: = *common::system::utilities::Logger::;
}
