Oliver says when I return with an exception, line and sourceURL, etc, properties will be added to it, and then I can use that later to pick up the line number.

That’s right.

...

You now say this doesn't seem happen, which means it would be impossible for me to pickup the line number (as there's no API for it.)

What I meant to say is that this will only happen if the exception is an object.

Or is it a third item, which is I need to create from a specific prototype TO get the line numbers added?

It just needs to be an object which can have properties set on it, as opposed to another kind of JavaScript value that can’t.

I prefer to answer questions on a public mailing list where everyone else can see the answers.

At this point you should try some things. I think you know enough about how this should work in theory, and you can let us know if things don’t work in practice.

Thank you, and I completely apologize for replying privately, I hit the "reply" instead of "reply all" and didn't notice this. I've bounced the reply to this list. [>] Brian
