I beg your pardon, but no, the meanings of the *standard* opcodes cannot vary. Only the special opcode meanings vary. See 6.2.4 #10: # By increasing opcode_base, and adding elements to this array, # new standard opcodes can be added, while allowing consumers who # do not know about these new opcodes to be able to skip them. r~
