Using named capture groups inside Ruby gsub blocks (regex)

I'm trying to use a named capture group inside a block in Ruby. $1 still works, but I'd like to reference it using the name I gave. 

"foo /(bar)".gsub(/(?<my_word> \(.*?\) )/x) do |match|
  puts "$1 = #{$1} and $my_word = #{$my_word}"
end

Expected:$1 = (bar) and $my_word = (bar)
