I think Tempfile#inspect is really confusing.
It says Tempfile object is a File, but it is not a File object.

% irb -r tempfile
irb(main):001:0> t = Tempfile.new("hoge")
=> #File:/tmp/hoge20120916-12354-uontdm
irb(main):002:0> t.is_a? File
=> false
irb(main):003:0>

in my opinion Delegator should be improved
so it shows that its a Tempfile, but is_a? should also show that its a File or IO

[headius (Charles Nutter)]

In my opinion, Tempfile should not use Delegator at all.

In JRuby, Tempfile actually is a File.

irb(main):001:0> require 'tempfile'
=> true
irb(main):002:0> t = Tempfile.new('blah')
=> #Tempfile:/var/folders/9j/yc18czps1x7cbsz76ccl__740000gn/T/blah.77744.52665
irb(main):003:0> t.class
=> Tempfile
irb(main):004:0> t.class.superclass
=> File
irb(main):005:0> t.is_a? File
=> true
irb(main):006:0> Tempfile.ancestors
=> [Tempfile, File, IO, File::Constants, Enumerable, Object, Kernel, BasicObject]
