Hello, In attachements you can find two patches that avoid using two additional OPs for shift and pop without argument. In the current blead ck_shift rebuilds the OP in this case and adds RV2AV(GV(@_ or @ARGV)) chain. Patches change that and use OPf_SPECIAL flag instead. I wrote two variants: 1) For @ARGV case old approach is used 2) op_private is used to choose between @ARGV and @_ later I prefer first variant, but it's up to you to decide: 1) the first variant drops two pp_* calls per shift; and adds &+if in pp_shift 2) the second drops the same two pp_* calls, but in all cases, however adds another &+if pair in pp_shift As shift; acting on @ARGV is limitted to scripts only then I don't think it worth to optimize tree size. -- Best regards, Ruslan.Thread Next
