See p. 68 of the third edition of the Camel book... "The __DATA__ token functions similarly to the __END__ token, but opens the DATA filehandle within the current package's namespace, so that files you require can each have their own DATA filehandles open simultaneously. For more information, see DATA in Chapter 28."
