Subject: class A::B verses module A ; class B

module A
   FOO = 99
end

module A
   class B
      puts "FOO is #{FOO}"  # => "FOO is 99"
   end
end

class A::B
   puts "FOO is #{FOO}"  # error
end

Comments?  I assumed the two forms were equivalent until I ran into
this.  Is there a reason they should be different?  I prefer the
second form, if only to save some indentation space.
