Then be more careful with your method of expression. But your method of expression is quite obviously the least of your problems ...

And quite obviously, you haven't bothered to read anything about the lambda calculus; it pre-dates electronic computers and programming as it is currently known. It is a formalism for describing and discussing computable functions. It is provable (and was, as part of the Church-Turing Thesis - look it up) that any computable function can be described in terms of the lambda calculus. If you still need a proof of soundness, disengage your bile ducts and start doing some reading.

And as I've told you on a few occasions now, there is no sounder basis than the lambda calculus for describing and reasoning about computable functions.

You have gone off the deep end now. Sadly, you're not even in the correct swimming pool.

Yes, you are very repetitious, both in your language and your ability to completely miss the point. Would you care to go back and read where this started from (that is: a question about where Erwin could find out about higher order functions) ?

It's only irrelevant and a waste of time because you have grabbed the wrong end of the stick and are shaking it with vigour.

The mention of undecideability was with regard to one of the fundamental issues of computability theory. Maybe if you'd bothered reading rather jumping off the deep end you would have known that.

What on *earth* has SQL got to do with this ? You have now wandered off into total irrelevance.

If this means what I think it means (and it's a stretch), then it would be both correct and irrelevant to the topic under discussion. Received on Tue Jun 20 2006 - 07:30:24 CDT
