Local::* is reserved for this purpose. From The Perl 5 Module List (Part 1, section 2.5):

 If developing modules for private internal or project
 specific use, that will never be released to the public,
 then you should ensure that their names will not clash
 with any future public module. You can do this either by
 using the reserved Local::* category or by using an
 underscore in the top level name like Foo_Corp::*.
