Somebody implemented part of it in the past, but it was based on the ability to observe the order of execution of comptime blocks, which is going to be removed from the language (probably already is). https://github.com/DutchGhost/zorrow https://github.com/DutchGhost/zorrow It's not a complete solution, among other things, because it only works if you use it to access variables, as the language has no way of forcing you.
