around hooks

As a developer using RSpec
I want to run the examples as part of a block given to a an arbitary function
So that I can control the environment in which it is run

Scenarios
  1. around hooks defined in a group are run
  2. argument passed to around hook can be treated as a proc
  3. around hooks defined globally are run
  4. before/after(:each) hooks are wrapped by the around hook
  5. before/after(:all) hooks are NOT wrapped by the around hook
  6. examples run by an around block should run in the configured context
  7. implicitly pending examples should be detected as Not Yet Implemented
  8. explicitly pending examples should be detected as pending
  9. multiple around hooks in the same scope are all run
  10. around hooks in outer scopes are run
around hooks defined in a group are run
Given
a file named "ensure_around_blocks_are_run.rb" with: 
describe "around filter" do
  around(:each) do |example|
    puts "around each before"
    example.run
    puts "around each after"
  end

  it "gets run in order" do
    puts "in the example"
  end
end
When
I run "rspec ./ensure_around_blocks_are_run.rb"
Then
the output should contain: 
around each before
in the example
around each after
argument passed to around hook can be treated as a proc
Given
a file named "treat_around_hook_arg_as_a_proc.rb" with: 
describe "around filter" do
  def perform_around
    puts "around each before"
    yield
    puts "around each after"
  end

  around(:each) do |example|
    perform_around(&example)
  end

  it "gets run in order" do
    puts "in the example"
  end
end
When
I run "rspec ./treat_around_hook_arg_as_a_proc.rb"
Then

examples run by an around block should run in the configured context
