The [Lemmas tutorial](http://rise4fun.com/Dafny/tutorial/Lemmas) states and proves a "distributive lemma" of the `count` function. However, the lemmas statement is not type correct, because `count` expects `seq<bool>` but the lemmas passes `seq<int>`.
The tutorial also refers to "How Dafny Works". I didn't find anything useful by googling that phrase. What is this referring to?
