Obviously, some concepts are shared. For example, the concept of "Less Than" is used in both C++ and Java. However, just as obviously, the fine points of the implementation differ. For example, Java does not allow my to concisely express the test 10 < 3 5 7 11 13. (C++ does let me express array comparison, there are limitations and complexities there, and I have to write a fair bit of the implementation myself.) Likewise, I'd have no problem expressing Double and Not-Or combined in the same word in either Java and C++, but in neither language are those particular concepts combined in a built-in word. > This brings up another point for me.
