It appears that by running a test in the core, there's a for loop that acquires 
all of the related elements and returns the first on a return i == 0;
   
  jquery.extend({ extend: {
   
  first: function(a,i){;return i==0;},
   
  a is selector, i is loop

Does :first make the selection faster? In other words, does it stop
the selection after the first item is found or it filters only after
all selections are found?
