Not a real problem in practice is just another way of saying rare. But given enough scale and enough time, rare things do happen, and they cost inordinately more programmer effort to chase down. I actually don’t mind if the compiler lets me ship very dumb bugs: those will be auto-rolled back out of production in seconds. It’s the subtle stuff that kills me.
