Sorry, meant -4 and 4.

NOT AT ALL.

[I don't under stand the "willing to" part, I either say something or I 
don't in a NG. Or did you forget a question-mark?]

I do not claim that I am right, I try to learn from discussion,
and, starting off with my argumented ideas, I am open to argumented 
arguments to the contrary.

"the only right one"?

I do not think there is a single right way of defining operator precedence 
in JS-parsing, but we still can argue about [personal or group] preference.
