   I wrote a test in RSpec core test suite and run using ruby master with an updated patch.

   ~/code/ruby_source_code/install/bin/bundle exec rspec spec/rspec/core_spec.rb

   --- a/spec/rspec/core/example_group_spec.rb
   +++ b/spec/rspec/core/example_group_spec.rb

          end
        end
   
   +    it "does not blow up with 'it' patch" do
   +      expect([1, 2].map { it.to_s }).to eq(["1", "2"])
   +    end
   +

   ~/code/ruby_source_code/install/bin/bundle exec rspec spec/rspec/core/example_group_spec.rb --example patch       [15:57:56]
   Run options: include {:full_description=>/patch/}

   It works. Same with all of the rspec-core test suite.

   Curious about what do you think about this Ruby proposal @JonRowe.
