-The above _slang_ code to be entered in the repl prints the numbers from 1 to 9. The repl may be compiled and executed using `dub run` in the project directory. Check the `example` directory for further further demonstrations.

+§ withinBounds @ 100 < ;

+§ buzz? @ 5 % 0 = ;

+This listing implements the common _FizzBuzz_ example in _slang_. It may be executed by compiling the REPL using `dub build` in the project directory and running `./slang example/fizzbuzz.slang`.
