Picture, if you will, a scene: A frog sits at the border of a lake, staring at a group of people mounting a new engine into a boat. No matter how long it watches them with its wide boggly eyes, it just can't comprehend what's going on. Eventually, it goes "RRRRibit?"
Now picture myself, sitting in front of a computer monitor, my eyes about as wide as the frog's, staring at a particular overly long line of code that has strong resemblance with a partial screenshot of a dwarf fortress game. My level of understanding is somewhere thereabouts with my green compatriot.
Eventually, I go "RRRRegex?"
