RSpec 3 and why I `expect(you).to care`
summary
RSpec 3 arrives after more than a year of work and a couple hundred contributors and makes concrete tradeoffs: the expect syntax becomes recommended to remove fragile monkey‑patching, automatic `should` is deprecated, a non‑monkey‑patch mode exists via config.disable_monkey, formatters now receive notification objects, verified doubles perform real method existence checks, several old helpers and hooks are removed or tightened, and the upgrade path is automated with Transpec.
