@myronmarston yeah, this was my initial implementation:
https://github.com/yelled3/rspec-expectations/commit/fe18c79d69908b6ad8151febab64114d3569a15c

maybe it's best to call it ```matcher_boolean_operators``
``` ruby
RSpec.configure do |config|
  config.expect_with :rspec do |expectations|
    expectations.matcher_boolean_operators = true
    # or
    expectations.matcher_boolean_operators = false
  end
end
```

@JonRowe WDYT?
