You don't need to.  You can simply use instance_eval directly:

File.open("foo", "w") do |x|
   x.instance_eval do
     puts "hello"
   end
end

Although I have to say I find this a bit clumsy.  I'd prefer

File.open("foo", "w") do |io|
   io.puts "hello"
end

Even if there were more IO operations I had to do on "io".  The piece 
above could be easily confused with printing to $defout.  Just my 0.02EUR...

Kind regards
