Each implementation divides the input string into words and applies a “word function” to each word and calls a “delimiter function” for each word boundary (the space between words).

Word boundaries are defined as follows:

• A set of consecutive non-letter/number/symbol e.g. foo _bar is two words foo and bar.
• A transition from a lowercase letter to an uppercase letter e.g. fooBar is two words foo and Bar.
• The second last uppercase letter in a word with multiple uppercase letters e.g. FOOBar is two words FOO and Bar.
