persona 0.10

persona is a Perl module born out of the need to be able to easily specify which subroutines of a module should be available (as in "compiled") in different sets of mod_perl environments (e.g. the visitors front end web servers, or the personnel's back-office web servers). This both from a memory, database and CPU usage point of view, as well as from the viewpoint of security.

This is most useful when using a database abstraction layer such as Class::DBI or DBIx::Class, where all of the code pertaining to an object is located in one file, while only parts of the code are actually needed (or wanted) on specific execution contexts.
