> Imagine that we have a secondary copy of the bytecode in the cache inside the code object and we mutate that instead. The key difference with the current cache infrastructure is that we don't accumulate all the optimizations on the same opcode, which can be very verbose. Instead, we change the generic opcode to a more specialised to optimize and we change it back to deoptimize. Yeah, I follow. As long as we keep the original list of opcodes we're good ;)
