README

        

Hijacks `do`/`while` statements with bitwise left shift (`<<`) to implement the `for`/`yield` syntax we all know and love :heart: from [scala](https://docs.scala-lang.org/tutorials/FAQ/yield.html).

If you mind not being able to use `do`/`while` statements with only bitwise left shift statements, then stay away.

However, if you like feeling alive and the taste of the kool-aid they're handing out in fp land, then look no further!

You can turn:

```js

getFoo("/api/foo").chain(foo => {

  return getBar("/api/bar").chain(bar => {

    return getBaz("/api/baz").map(baz => {

      return foo + bar + baz

    });

  })

});

```

into:

```awesome-sauce

do {

  foo << getFoo("/api/foo")

  bar << getBar("/api/bar")

  baz << getBaz("/api/baz")

} while(

  foo + bar + baz

)

```

Limitations:

  1. do body must only contain `<<` expressions

  2. `while` test must only contain a single expression

  3. Coworkers will loathe you when you try to explain monads to them.
