What is the best algorithm for overriding GetHashCode?
... quite how important that is.)
This is better than the common practice of XORing hashcodes for two main reasons. Suppose we have a type with two int fields:
XorHash(x, x) == XorHash(y, y) == 0 for all x, y
XorHash(x, y) == XorHash(y, x) for all x, y
By the way, the earlier algorithm is the one c...

What's the (hidden) cost of Scala's lazy val?
...) and initializes the target field in a synchronized block if the relevant xor of the bitmap indicates it is necessary.
Using:
