Heh. I remember a time back when I worked at Google, and we're using a proprietary internal language to construct some monitoring stuff. It took three of us a day to implement some simple thing that was a line or two of code, so opaque and intractable the language was. When we got it to do what we expected, we still weren't quite sure it was really correct. It was really kind of an existential moment where we collectively wondered, "wtf are we doing?"
