@Luke73 i tried to read a book on it once... It actually got so thick i had to give it... The shooting your grandfather, time travelling paradox is a good example

@Convivial Self-references can make things pretty complicated for sure. Though recursion often makes things simpler, they usually work with devide-and-conquer. You devide a big problem in smaller ones which are easy to solve.

@Luke73 thanks for that addendum

@LordShadowfire Which joke? I only see my own post 😞

@Luke73 No, you see my answer.

@LordShadowfire Yes, you're right.
