  New Revision: 62732

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62732

  Log:
    Speed up func1.func2 completion by using Set for ignored modules
    
    And thus avoiding Module#name calls. Those are slow, especially in
    larger projects, with lots of anonymous modules.
    
    [Fix GH-1798]
