Captures one or more consecutive word characters (letters, digits, underscore) or literal dots into a single group. Because dots are included, it effectively matches path segments or filenames with extensions like 'my.folder.name'.

Useful for simple path parsing, filename extraction, and capturing identifiers that may contain dots.
