A couple weeks ago I asked how you "join the conversation" but based on feedback I got, I don't think I communicated well. I think people thought I meant "which blogs do you read?" What I really meant was: when you write a blog entry, where do you post the link so that it's seen by people who are interested in that subject?

So for example, when I write about Perl, I post to blogs.perl.org. I want to blog about other topics too, like web development (JavaScript, CSS, etc); lifehacks; Unix, L…

This situation arose recently and it got me curious...

What if you needed to access an algorithm in a very simple class method, but the functionality of the class is significant and would be a pain in the ass to set up and create an object in, not to mention resource-intensive, all to use one small function...

You could copy the algorithm, but what if it changes? Then you'll have to change it twice. That's no good. I don't like either option.
