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. + +By unimporting via no you can tell namespace::clean to start collecting +functions for the next use namespace::clean; specification. |
