Is there a reason to have /hidden/ parameters? Which gives me: This is ok at least as it is pointed out that 'value' was used but not defined. But in this case: It give this: I would think that this could be a source of bugs as someone may pass a parameter by name and if the parameter name doesn't exist it would continue on it's merry way using a variable that was defined somewhere else in the file causing hard to find bugs. Also, is there a way of putting out filenames and line numbers where the warning occurred?
