FYI, D has https://run.dlang.io/ https://run.dlang.io/ I actually use it regularly to run small snippets of code. It's integrated into the documentation, for example https://dlang.org/phobos/std_algorithm_searching.html#.find https://dlang.org/phobos/std_algorithm_searching.html#.find, so that you can play with the function to see how it works.
