+This function is useless for Rascal programmer's as it is a part of the under-the-hood implementation of values.
+You can use a value directly as a lookup key. The internal data-structures probably use this hashCode for
+optimal lookups in `O(log(size))`.

+We use this function to diagnose possible performance issues caused by hash collisions.
