in reply to Guaranteed unused namespace on CPAN

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::*.

    The second suggestion is violated by the standard distribution (AnyDBM_File, GDBM_File, NDBM_File, SDBM_File), although it could be argued they are just .pm files, and don't use class names with '::' in them. But a quick scan of the file sources/modules/02packages.details.txt.gz shows several name spaces that use an underscore in the first component. (CDB_File, DB_File, DWH_File, heavy_template).

    I think that in theory the way Perl and CPAN works is that it is very hard to make sure there are no name clashes. I think that practise has shown that there's not much of a problem.
