"+" (a, b) vs "+ (b, a) is not about order of evaluation; it is about association of parameters. To be more clear, we should be saying: 'a + b' is equivalent to "+" (left => a, right => b); it is never equivalent to "+" (left => b, right => a); whether b or a gets evaluated first is an orthogonal question. > I should stop wrestling with pigs.

What I'm getting from your postings is that you are having a hard time actually hearing what Hymen is saying. You keep responding to different points, and now you are resorting to ad hominem attacks. Misunderstandings are to be expected in newsgroups! -- -- Stephe
