Which brings us back at the Turing completeness argument of being
essential ;-). I'm prepared to argue that it allows for separation of
concerns in a way that is very hard otherwise (like asking the user to
retry an operation - a one-liner in Smalltalk, nigh impossible in Java).
This sort of 'clean code' functionality *is* important.
