  • * You shouldn't be importing functions from a superclass and nobody's stopping you from adding a "use Baseclass" if you really want to.

    True, but it's frustrating to inherit from a base class which might need arguments passed to its import method. There was some discussion about this on P5P and I recall someone suggesting something like this:

    use base
      'SomeClass',
      'SomeOtherClass' => { import => [ qw/import args/ ] };

    That would be backwards compatible and get around that limitation

    • Also import() isn't just used to, umm, import. It's quite a common idiom to use it to pass global settings to a class, such as telling it to put temporary files in a particular place, or changing its default timezone. Those still have their place in OO programming.

      Even so, I don't consider this to be a problem with base.pm. If I really need to do things like that, the work-around is trivial.
