unnecessary_ constructor_ name
                  Unnecessary '.new' constructor name.
Description
#
                    The analyzer produces this diagnostic when a reference to an unnamed
                    constructor uses .new. The only place where .new is required is in a
                    constructor tear-off.
                  
Example
#
                    The following code produces this diagnostic because .new is being used
                    to refer to the unnamed constructor where it isn't required:
                  
var o = Object.new();
                      
                      
                      
                    Common fixes
#Remove the unnecessary .new:
var o = Object();
