words

Splits s into its words, keeping their original casing.

A word ends at any non-alphanumeric character, before an uppercase letter that follows a lowercase letter or a digit (userName, v2Beta), and before the last capital of an acronym run (HTMLParser gives HTML, Parser). Use one of the *_case helpers instead if you want the words lowercased and rejoined.
