libnamespace-clean-perl 0.11-1 (i386 binary) in ubuntu karmic

 When you define a function, or import one, into a Perl package, it will
 naturally also be available as a method. This does not per se cause problems,
 but it can complicate subclassing and, for example, plugin classes that are
 included via multiple inheritance by loading them as base classes.
 .
 The "namespace::clean" pragma will remove all previously declared or imported
 symbols at the end of the current package's compile cycle. Functions called
 in the package itself will still be bound by their name, but they won't show
 up as methods on your class or instances.
 .
 It is also possible to explicitely tell "namespace::clean" what packages to
 remove when the surrounding scope has finished compiling.
 .
 You can tell "namespace::clean" that you want to clean up another package
 instead of the one importing.
