Has it actually been mapped thoroughly? Is there actually a common language/terminology across Ruby, Python, Lisp, Javascript, Go, C++, etc? I've noticed that terms & definitions subtly or not-so-subtly vary from programming language to programming language, so I imagine it's pretty tricky to come to any sort of consensus.
