 /*===========================================================================
   Notes:
+
+  (*) Opcode OP_LFALSESKIP is used to convert a condition to a boolean
+  value, in a code equivalent to (not cond ? false : true).  (It
+  produces false and skips the next instruction producing true.)
+
+  (*) Opcodes OP_MMBIN and variants follow each arithmetic and
+  bitwise opcode. If the operation succeeds, it skips this next
+  opcode. Otherwise, this opcode calls the corresponding metamethod.
+
+  (*) Opcode OP_TESTSET is used in short-circuit expressions that need
+  both to jump and to produce a value, such as (a = b or c).
+
   (*) In OP_CALL, if (B == 0) then B = top - A. If (C == 0), then
   'top' is set to last_result+1, so next open instruction (OP_CALL,
   OP_RETURN*, OP_SETLIST) may use 'top'.
