Yes. But even then,

module A; end
module A::B
  ...
end

is different to

module A
  module B
    ...
  end
end

in the way that constants are looked up.


>> module A; FOO = 123; end
=> 123
>> module A::B
>> puts FOO

NameError: uninitialized constant A::B::FOO
  from (irb):3
  from :0
>> module A; module B
>> puts FOO
>> end; end
123
=> nil
