Related question to the SHA/MD5 hash functions: could those be pure?
Weakly pure, yes - but for what?
In general, if a function _can_ be pure, it _should_ be pure. If it can be and
it isn't, it artificially restricts the types of functions which can call it.
Yes, Johannes probably want to mark uuid hash gen as pure. I just wanted
to know if its something important as my code used memcpy which is impure.
