I remember learning Prolog, it was tricky to wrap my mind around it, it wasn’t like any other language. The day I finally “got it” I was very happy, until I realized all the other languages I had previously learned, no longer made any sense.
I remember taking a PL class in undergrad, learning Prolog as one of a handful of languages. During that section my brain started to want to "bind" variables to things as I was going about my day, it was very weird.
