I don't like the way expect syntax reads for one liners with implicit subjects. What was this changed for? Is there a problem with that matcher? rspec maintainers [suggest using should](https://github.com/rspec/rspec-expectations#one-liners) even when the syntax is set to expect.

Another alternative would be `specify { expect(flash[:notice]).to match(/double check the URL/i) }` which I'm not sure is much nicer, honestly.
