If Rust is one, yeah I have to fight that compiler but it's because it's doing its job and not letting me do invalid things. Not because the compiler has some feature "not yet implemented" or has bugs.
Also, is anyone familiar with the weirdness with tuples in Swift? All I remember is they never worked the way I expected, and for some reason something in our code specifically worked for tuples up to size 5.
Swift only got variadic generics fairly recently, and before that you couldn’t write code which was generic over tuple size. Instead you had to codegen versions for each size of tuple you needed to support.
