Well, a sceptic like me is bound to wonder why such a non-function is
provided in a purely functional language. What really worries me is
that the damage isn't localised. If you allow such things you can never be
sure that any function really is a function, without careful scrutiny of all
the code it's dependent on.

What is wrong with Java and C# arrays? (I have never used either).
