Exemplar is passing all 7 tests of TestExemplar.py, which include Fizz Buzz, a leap year predicate, and a prime number
predicate. You can see these inputs as fizz_buzz.exem, leap_year.exem, etc.
But
- that success is partly by overfitting to the problems.
- there is no recovery from an incorrect guess of what an assertion represents.
- the assertion specifications are too demanding.
So demotion of the assertions to hints and other improvements are planned.
