high bar for style guide waivers on such restrictions, because waiving such rules often directly risks compromising program correctness. Avoid constructs that our average C++ programmer would find tricky widely used code, it may be 2 more acceptable to use trickier language constructs, because any benefits of more complex implementation are multiplied widely by usage, and the cost in understanding the other issues. • The performance costs of value semantics are often overestimated, so the performance benefits of ownership transfer might not justify the readabil- ity and complexity costs. • APIs that transfer
