Difference between blocks, procs and lambdas.

Blocks are not objects and can't be manipulates as objects. With procs and lambdas is possible to
create objects that represents a block.

Procs and lambdas have the 'call' method, that executes the block code associated in their creation.

A proc behaves like a block, different of lambdas that behaves like a method. For that reason,
lambdas need to receive the exact number of parameters defined in your declaration.

RSpec.configure do |config|
  config.extend VCR::RSpec::Macros #deprecated
end
 
# This gives us access to the use_vcr_cassette method:
describe Reviewed::Article do
  use_vcr_cassette 'article/grill'
