perl5i performs the valuable services of integrating several useful but disparate extensions into a single working whole, which helps to identify missing features and to encourage collaboration. It's also much easier to install and to enable.
I see it as an experiment as to where Perl 5 could be. Even though I might not use it outside of personal projects, it's still useful.
I think it's lost on me because a lot of these simple problems it allows you to solve with simple code are also equally specific problems. (In a "how many times have you written this routine?" sense, my answer is almost always "once" or "never.") I haven't seen a really good example without a better solution so I've got that "use Kitchen::SinkToo;" feeling.
That's not a bad idea for personal projects if it does save you time. Otherwise I'm not so sure. Experimenting is good though.
