Pretty brief description, but... from what I gather, it's nothing more than having a package that contains a bunch of methods that you allow to be exported and then having other classes import them?

I have a ::Util class I fill with a handful of methods that don't particularly belong anywhere and aren't worth having their own class which I then import into other packages. Is this what is considered a "mixin"?

Sorry if I come across a bit daft. Using Perl as a first exposure to OOP is brain-damaging.
