I committed a first cut at blockless Givens/Whens/Thens to RSpec’s
Take a look at examples/story/calculator.rb to see what’s going on.
I’ve also got a cut at the plain text parser checked in, but it’s not
hooked up to anything yet. However, now that we can do blockless GWT,
hooking the parser up to the rest is just a matter of a simple adapter
and logistics. Look for it in the next few days.
