Broken example

See original GitHub issue

Named taggedSum from the example is broken (Node 6.9)

const daggy = require('daggy')
const Option = daggy.taggedSum('Option', {
  Some: ['x'],
  None: [],
})

$ node example.js 
/Users/gleb/git/training/node/daggy-maybe/node_modules/daggy/daggy.js:149
            definitions[key] = tagged.apply(null, constructors[key]);
                                      ^

TypeError: CreateListFromArrayLike called on non-object
    at Object.taggedSum (/Users/gleb/git/training/node/daggy-maybe/node_modules/daggy/daggy.js:149:39)
    at Object.<anonymous> (/Users/gleb/git/training/node/daggy-maybe/example.js:2:22)

One can skip string 'Option' but then there are no Option.Some.is methods

If you’re using the version provided by npm, you’d need to follow the docs there as the current state of the repository and the current version available on npm are not the same (https://www.npmjs.com/package/daggy).

On github you could see them here: https://github.com/fantasyland/daggy/tree/v0.0.1/
