... and then to claim that it doesn't really matter because you don't think people care about this.

That has never been my line of argument. Never.

The only reason I said that some people don't care about that is because you made a point about people in finance and audit being very strict on accuracy, and my 20+ years experience with them tells me that this is just not true.

To briefly repeat the general gist of my first answer to you in this thread: finance and audit people will certainly bend over backward (and cause you and me and others many headaches and problems, and perhaps even kill their moms) to make things look right, but accuracy is a much lesser concern for them. I don't want to repeat myself more than that, so please look at this post for a somewhat detailed example of what I mean: Re^13: Reasons for Using Perl 6.
