A string is essentially an array of characters. In Smalltalk a String is a subclass of ArrayedCollection, which means it supports the Collection protocol. StringIterate implements the methods available on the collection protocol that make sense for Strings. Some methods are over-specialized, in the form of englishToUppercase() which is a fast form of uppercase, but does not work for different locales.
