What Ruby version are you using?

I've tried with Ruby 2.6.3 and it behaves exactly like in the documentation:

2.6.3 :001 > require "ostruct"
 => true
2.6.3 :002 > data = OpenStruct.new("country" => "Australia", :capital => "Canberra")
 => #<OpenStruct country="Australia", capital="Canberra">
2.6.3 :003 > data.to_h
 => {:country=>"Australia", :capital=>"Canberra"}
2.6.3 :004 > data.to_h {|name, value| [name.to_s, value.upcase] }
 => {"country"=>"AUSTRALIA", "capital"=>"CANBERRA"}

With Ruby 2.5.1 it behaves like in your example:

2.5.1 :004 > data.to_h {|name, value| [name.to_s, value.upcase] }
 => {:country=>"Australia", :capital=>"Canberra"}

If you check Ruby 2.5.1's version of the documentation - ruby-doc.org/stdlib-2.5.1/libdoc/o... - you'll notice that data.to_h does not support the additional block, that's why it returns the unchanged format.

Wow! Thanks, @rhymes ! I have 2.5.3 installed, so you're correct. Looking over at rubyinstaller.org/, I see the recommendation to stay with 2.5 for now.

For the post I'm writing, I think I'll specify which Ruby version I'm writing about.

Yeah, unfortunately Ruby's support on Windows isn't great :(
