Why is XOR the default way to combine hashes?
...om (1-bit) inputs, the AND function output probability distribution is 75% 0 and 25% 1. Conversely, OR is 25% 0 and 75% 1.
The XOR function is 50% 0 and 50% 1, therefore it is good for combining uniform probability distributions.
This can be seen by writing out truth tables:
a | b | a AND b

Delete element in a slice
... arguments to a variadic function.
So what this line does:
a = append(a[:0], a[1:]...)
is essentially:
a = append(a[:0], a[1], a[2])
Now, you may be wondering, why not just do
a = append(a[1:]...)
Well, the function definition of append is
func append(slice []Type, elems ...Type) []Type
