Immutable data

What kind of idiot needs to have his data kept constant to keep himself from breaking something? If you can't keep your shit in order without stupid artificial constraints, then you don't know shit about programming.

Again, that's changing the variables.  When I say `Data is trivially immutable' I really mean that.  If a register holds 0111010110110101, the contents of the register may change, but 0111010110110101 will never change.  It just may not be held by a variable at any particular time.  Yes, it's a fucking copout, but it's also true.
