Start once again from Exercise 11-2. Because the length of words is exorbitant (five letters, oh my!), make sure that all names in this namespace can also be qualified with wrds (four letters, already much better!) and w (one letter, perfect!). Use two different techniques for this. (For the record, neither cryptic acronyms such as wrds nor one-letter identifiers such as w have their place in production-quality code: clarity always trumps compactness!)
