As a sort of sequel to my footnote about
printf being Turing complete on @drummyfish’s Iceberg topic, here’s a list of things that are accidentally turing complete. (Incidentally, this list includes a lot of the Turing completeness examples from the iceburg.)
Fittingly, I wasn’t actually intending to make a topic about this, I just stumbled upon this accidentally and thought it would be worth sharing.
The one I’m most surprised about is Java’s generics being Turing complete. Unfortunately the proof is an academic paper I have no hope of understanding.
