All branches will diverge from the stem: from Elm to Derw

All branches will diverge from the stem: from Elm to Derw.
Forgive the fancy title, but I felt it fit this month’s Derw improvements well. Originally, Derw was intended to be an Elm with better support for TypeScript. As more TypeScript support is added, Derw deviates further from Elm. To write good, modern TypeScript code, you need to be able to handle async/await properly. No callback hell. To do so in an Elm-like language, the obvious path to follow was do-notation from other ML languages. So, do-notation was added to Derw.
