How in the world does SimpleDelegator#method work?

• SimpleDelegator subclasses BasicObject, which does not provide a method method.

What status code should this return?

I'm working on an HTTP-compliant API for a service. We've got a situation where we're not sure what status code to return.

During this time before the first batch is ready, when a client

its isn't core to RSpec. One the of the focuses of RSpec is on the documentation aspects of tests. Unfortunately, its often leads to documentation output that is essentially lies. Consider this spec:

User = Struct.new(:name, :email)

describe User do
  subject { User.new("bob") }
  its(:name) { should == "bob" }
