point taken.

If we are going to have any kind of explicit grouping let's use the

Ok, let's not have it then. I really don't think parenthesis' should be a
part of end-user language, but I'm willing to reconsider if there are
objections.

Ok, I change my mind back (for now). OR could have precende. The reason why
I am hesitating is because people might find it outrageous that AND doesn't
have precedence as is standard... Anyway I'm willing to take that risk :-) I
would like more opinions on this though.

No, _we_ have to decide something :-) Anyway things might change when we go
into public evaluation, it's only about the proposal for now.

Cheers,
Mikkel
