proposal: archive/zip: File.OpenRaw() should return io.NewSectionReader about go

[seankhliao]

changing the function return signature isn't a backwards compatible change.
you can type assert if you need the other methods

I modified my post, I meant to put "ReadSeeker" it has been updated. Since it also implements reader, wouldn't it work fine and be backwards compatible since it implements the functions?

OH! so I can just do this?

r,_ := f.OpenRaw()
return r.(io.ReadSeeker), nil
