Use of Ramda with Bluebird

ramda-with-bluebird.js

var Q = require('bluebird'),
    R = require('ramda');

var shouldError = false;

var a = function (arg) {
    return new Q.Promise(function (resolve, reject) {
        resolve("[a] resolved");
    });
};

var b = function (arg) {
    return new Q.Promise(function (resolve, reject) {
        if (shouldError) {
            reject("[b] rejected");
        } else {
            resolve("[b] resolved");
        }
    });
};

var c = function (arg) {
    return new Q.Promise(function (resolve, reject) {
        resolve("[c] resolved");
    });
};

var steps = R.pPipe(a, b, c);

steps().then(function (finalResponse) {
    console.log(finalResponse);
}).catch(function (err) {
    console.log(err);
});

Now seems to be called pipeP().
