My confidence soars.
In other news, I had an epiphany today: I know this shit. Today, I'm teaching a programming language called PERL, which has a feature known as regex's (regular expressions). Regex's are difficult to understand, but easy to use, impossible to read, and tricky to create. The pack a great deal of bang for their buck though... and are extremely powerful.
I know this shit cold. I'm so proud!
