[Rspec-devel] self naming specs

Guys, I started looking at the self-naming spec idea and there's a few
complications that make me wonder whether it's really feesible. Let me
know what you think:

First, let's imagine a spec like this:

context "An empty stack" do

  setup do
    @stack = Stack.new

  specify do

  specify do
    @stack.size.should.be 0


What we'd want this to produce would be this:

An empty stack
- should be empty
- size should be 0

The problem is that the should helper has know way of knowing
definitively whether its caller is the subject of the context (the
stack) or something else, like the Fixnum resulting from @stack.size.
We could, conceivably do something like this:

context "An empty stack" do
  subject @stack = Stack.new

but then we start adding confusion to reduce the duplication. The
self-naming spec would be a cool feature, but right now things are
very, very clean. I don't want to fuck that up.
