The "dynamic borrow checker" is called a RefCell, and it's a footgun you have to explicitly point at your foot and pull the trigger, not something you'd randomly stumble upon. It's something you'd use very situationally, after you really considered all your options and found out you couldn't do it by writing normal code instead, and this is a very rare situation. Think of them like Python's metaclasses.
