Subject: newbie q on class Foo::Bar

What's the point of a class-within-a-class? For example, I take it that
I can say:

class Foo
  class Bar
    def whatever
    ...

And then I can say

my_foo_bar = Foo::Bar.new

For example, isn't that what something like File::Stat is?

My question is, am I right about this, and if so, what's the point of
doing so? I take it that Bar is not magically related to Foo - it can't
see Foo's methods or anything like that, can it? So is this merely a way
of using a class (Foo) as a namespace so that related classes (like Bar)
are all in one place? Thx - m.
