Oddly, that article doesn't link to the most interesting modern use. It's for security exploits. People have built compilers that output a binary that consists largely of return addresses that point into the middle of normal functions.
This deserves a bit of clarification: ROP is an application of threaded code technique. Conventional Forth (proto-father of stack-based/concatenative languages, alongside with Joy) is based on indirect-threaded code (ITC), so the connection between ROP and stack-based programming is rather indirect (pun intended).
For anyone interested, Book by Loeliger [1] and "Moving Forth" series [2] are essential readings on this topic.
