REPL

console
The `nix repl` command opens a [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop) which can be handy to debug or play with the language. As with most REPLs, `CTRL-c` allows you to cancel a command, and `CTRL-d` allows you to quit the REPL. 
$ nix repl
The nix language is a function language. If you've done some OCaml before, it should not be too hard to ramp up. I recommend to read the Nix page on [learnXinYminutes](https://learnxinyminutes.com/docs/nix/), although it would be nice to have explanations on this page.
