Consider the following code in file "zzz.rb":

class ZZZ
  P = D = 1
  private_constant :P
  deprecate_constant :D
end

After loading the file, accesses to ZZZ::P and ZZZ:D cause an exception and a warning respectively.

$ ruby -r./zzz -e ZZZ::P
Traceback (most recent call last):
-e:1:in `<main>': private constant ZZZ::P referenced (NameError)

$ ruby -r./zzz -e ZZZ::D
-e:1: warning: constant ZZZ::D is deprecated

But autoloading the file nothing happens.

$ ruby -e 'class ZZZ;autoload :P,"./zzz.rb";end; ZZZ::P'

$ ruby -e 'class ZZZ;autoload :D,"./zzz.rb";end; ZZZ::D'

After requiring the file in ordinary way, they works.

$ ruby -e 'class ZZZ;autoload :P,"./zzz.rb";end; require "./zzz.rb"; ZZZ::P'
Traceback (most recent call last):
-e:1:in `<main>': private constant ZZZ::P referenced (NameError)

$ ruby -e 'class ZZZ;autoload :D,"./zzz.rb";end; require "./zzz.rb"; ZZZ::D'
-e:1: warning: constant ZZZ::D is deprecated
