Issue #7027 has been updated by Hanmac (Hans Mackowiak).


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

Bug #7027: Tempfile#inspect is Confusing

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>
