Issue #6489 has been reported by yimutang (Joey Zhou).

----------------------------------------
Bug #6489: A File instance changes its class to IO
https://bugs.ruby-lang.org/issues/6489

Author: yimutang (Joey Zhou)
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]


I don't know whether it is a bug, or a feature.

1.9.3p194 :001 > f = open('xxx','w')
 => #<File:xxx> 
1.9.3p194 :002 > f.class
 => File 
1.9.3p194 :003 > f.__id__
 => 80452110 
1.9.3p194 :004 > f.reopen(STDOUT)
 => #<IO:<STDOUT>> 
1.9.3p194 :005 > f.class
 => IO 
1.9.3p194 :006 > f.__id__
 => 80452110 

You see, an object(id:80452110) changes its class from File to IO.
Is it ok?
