It is a PathSet object - the easiest way to check this is to type:
ActionView::Base.new('app/views').view_paths.class

What you see when you call "ActionView::Base.new('app/views')" is just
a string representation of the object. To assume when you look at the
to_s output in the console that the original object is what the to_s
produced is like looking at a black and white photograph and assuming
the subject of the photo was black and white.
