 you call a matcher in an example without a String, like this:
ify { object.should matcher }
his:
 should matcher }
c expects the matcher to have a #description method. You should either
a String to the example this matcher is being used in, or give it a
ription method. Then you won't have to suffer this lengthy warning again.
