A change in Clojure 1.7 beta1 broke one of the ways in which Midje
deduces function names. I've fixed that and made it a beta release.
It also contains better reporting for diffs of collections and strings,

https://github.com/andersfurseth/flare That
improvement doesn't apply to collection checkers or the =not=> arrow.
I've started work on that, but it won't be in 1.7 unless the final
release of Clojure 1.7 takes longer than I expect.
If you plan to use Clojure 1.7, I encourage you to try out the Midje beta.
