Page 241 / Exercise 8-2: "exception" should read "expression"

[thederz]

Exercise 8-2 reads: "8-2. Implement a PrimeNumberRange class that can be used in a range exception to iterate over all prime numbers less than a given value ..."

Exercise 8-2 should read: "8-2. Implement a PrimeNumberRange class that can be used in a range expression to iterate over all prime numbers less than a given value ..."
