CALLER_ARG_SPLAT is not necessary for method_missing. We just need to unshift the method name into the arguments. This optimizes all method_missing calls: * mm(recv) ~9% * mm(recv, *args) ~215% for args.length == 200 * mm(recv, *args, **kw) ~55% for args.length == 200 * mm(recv, **kw) ~22% * mm(recv, kw: 1) ~100% Note that empty argument splats do get slower with this approach, by about 30-40%. Other than non-empty argument splats, other argument splats are faster, with the speedup depending on the number of arguments.
