# SYNOPSIS

A tiny flow control module that destructures.

# CODE

```js

module.exports = f => {

  if (!f.prototype.throw) return function() {

    const args = Array.from(arguments)

    return f.bind.apply(f, [null, ...args])

  }

  const gen = f()

  ~function nextCallback() {

    const next = gen.next(Array.from(arguments))

    if (!next.done) next.value(nextCallback)

  }()

}

```

# EXAMPLE

```js

const { run, wrap } = require('yl')

const fs = require('fs')

const assert = require('assert')

run(function* () {

  const [statError, s] = yield wrap(fs.stat)('./index.js')

  if (statError) return console.error(statError)

  const [readError, f] = yield wrap(fs.readFile)('./index.js')

  assert.equal(f.length, s.size)

})

```

Or you could wrap everything initially...

```js

const { run, wrap } = require('yl')

const fs = wrap(require('fs'))

const assert = require('assert')

run(function* () {

  const [statError, s] = yield fs.stat('./index.js')

  const [readError, f] = yield fs.readFile('./index.js')

  assert.equal(f.length, s.size)

})

```
