> Right now, every bytecode gets a new instance of ByteCode. This is necessary for those bytecodes which take arguments, but the NoArgumentForm bytecodes don't need this. Since they constitute a large part of the bytecode set, caching a single instance of these bytecodes leads to considerable savings.
