Benchmarker Class Task - Syntax Error

I keep getting this error when trying to submit my code: SyntaxError: eca5dda5-cd7f-4323-97ce-e5a88aaaf7ab.rb:33: syntax error, unexpected keyword_end, expecting end-of-input

But, I can't see what I have done wrong. Not sure if it's a bug, or if it's my error, could someone point it out to me?

Many thanks!

simple_benchmarker.rb 
class SimpleBenchmarker
  def run(description, &block)
    start_time = Time.now
    block.call
    end_time = Time.now
    elapsed = end_time - start_time

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"
  end
end

benchmarker = SimpleBenchmarker.new
  benchmarker.run "description" do
  end
end

Hi Mile,

You are pretty close. You want to put the description string inside parentheses, and some block of code between the do and end. You also have an extra end at the end of your code. e.g.

 class SimpleBenchmarker
  def run(description, &block)
    start_time = Time.now
    block.call
    end_time = Time.now
    elapsed = end_time - start_time

    puts "\n#{description} results"
    puts "Elapsed time: #{elapsed} seconds"
  end
end

benchmarker = SimpleBenchmarker.new
benchmarker.run("description") do
  puts "All done!"
end
