    Compose generator and async/await middleware like koa. Allows to use both generator functions and async/await functions.

    var compose = require('composition');
     
    var stack = [];
     
    // generator functions
    stack.push(function* (next) {
      yield next;
    });
     
    // regular functions that return anything
    // but they should be promises!
    stack.push(function (next) {
      return Promise.resolve(true);
    });
     
    // async/await functions
    stack.push(async function (next) {
      return await Promise.resolve(true);
    });
     
    // compose it into a function
    var fn = compose(stack);
     
    // this function returns a promise
    fn.call(this).then(function (val) {
      console.log(val);
    }).catch(function (err) {
      console.error(err.stack);
      process.exit(1);
    })
