To be fair, some things are a pain in the ass to google properly (especially if you aren't familiar with the topic in the first place). Also, documentation always makes more sense when you already know the topic. :P

That is not what I'm talking about since the OP was able to find perlop, but the problem was, it merely listed ||= it didn't explain much about it.

You had to read large chunks of perlop to figure out ||= is two operators in one, assignment and logical-or, and even then it didn't explain truthiness

On truthiness

How ||= works , its FAQ even though it doesn't search that way :)
