This idiocy "if two have distinct single provenance, the result has empty provenance" invalidates real code w/no althttps://twitter.com/bmastenbrook/status/725048588053655554 …

@RichFelker Another case is a swap of pointers via xors. But are you sure this is an example of real code? -
@ch3root XOR linked list is a real-world need for implementing some things where you don't have space for 2 pointers. -
@ch3root In-place algorithms on data structures where you only have one modifiable pointer-size slot. -
@ch3root "XOR swap" on the other hand is cargo-cult-"optimization" BS.
