Using repl.it for interactive examples
Currently the two problems I see with embedding repl.it are the bloated interface for our needs (files on the left, which we don't need, and the big bar over the editor) and that every Haskell program of more than one line needs a main function, which just obscures the code examples. I think a better solution if we want easy interactivity but also to make it readable is to link important code examples to interactive pre-populated repl.it editors.
