Use operator overloads judiciously [6]
Define operators primarily to mimic conventional usage [1]
Place spaces on either side of a binary operator [2]
Define operators consistently with each other and whenever appropriate provide semantics similar to those of standard types [3]
Pay attention that the semantic/intended priority of your overloaded operators matches the priorities of C++ operators [4]
Implement binary operators as free functions [5]
