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:>
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?

Hello,

FYI: The rdoc of IO#reopen says:

• call-seq:

• ios.reopen(other_IO)         -> ios
  

• ios.reopen(path, mode_str)   -> ios
  

• Reassociates ios with the I/O stream given in
• other_IO or to a new stream opened on path. This may
• dynamically change the actual class of this stream.
