McConnell, Steve. Code Complete. Redmond, Wash.: Microsoft Press, 1993. Much of the book describes how to work around programming-language limitations, advice which applies to RDLs as well as any other language. Chapter 21 describes the effect that program size has on project activities and therefore on the potential that an RDL has to reduce overall development time.
