Cling is absolutely amazing to get the REPL mood combined with C++. In my view, every programming language should have a REPL because it is so damned explorative and allows for quickly playing with stuff and developing ideas. I frequently code python in the REPL and then copy&paste working lines into a text editor. If you like cling, look into Xeus, an adapter for Jupyter notebook.
