    Lint: No Assignment of Exception Param
    
    Disallow Assignment of the Exception Parameter.
    
    If you set the exception parameter it makes it impossible to track the
    error from that point on.
    
    Example:
    
        try {
            // code
        } catch (e) {
            e = 10;
        }
