Yea, it is really amazingly nice to have this. People don’t like Pascal, even though it’s a nice, readable and very fast language. Compile time wise, modern languages are a joke, but not a funny one. I can compile a million lines of pascal faster than updating a hello world typescript site. I have been looking how to add a borrow checker to fps with minimal damage. It seems with compiler directives it can work. The compiler can tell you how many frees are not guaranteed.
