Functions called in the package itself will still be bound by their\nname, but they won't show up as methods on your class or instances.\n\nThis module is very similar to namespace::clean, except it will clean all imported functions, no\nmatter if you imported them before or after you \"use\"d the pragma. It will also not touch\nanything that looks like a method.\n\nIf you're writing an exporter and you want to clean up after yourself (and your peers), you can\nuse the \"-cleanee\" switch to specify what package to clean:\n\npackage My::MooseX::namespace::autoclean;\nuse strict;\n\nuse namespace::autoclean (); # no cleanup, just load\n\nsub import {\nnamespace::autoclean->import(\n-cleanee => scalar(caller),\n);\n}\n\nWHAT IS AND ISN'T CLEANED\n\"namespace::autoclean\" will leave behind anything that it deems a method. For Moose classes,\nthis the based on the \"getmethodlist\" method on from the Class::MOP::Class. For non-Moose\nclasses, anything defined within the package will be identified as a method. This should match\nMoose's definition of a method. Additionally, the magic subs installed by overload will not be\ncleaned.\n", "subsections": [] }, "PARAMETERS": { "content": "-also => [ ITEM | REGEX | SUB, .. ]\n-also => ITEM\n-also => REGEX\n-also => SUB\nSometimes you don't want to clean imports only, but also helper functions you're using in your\nmethods.
