As in the following example, I am defining the return type of createServer() to be a MockServer interface (which is empty), instead of "Server" as defined in https://github.com/facebook/flow/blob/master/lib/node.js

Shouldn't this work, since an empty interface can stand in for any class?

/* @flow */
var http = require("http");

interface MockServer {}

Basho: Shell pipelines with the goodness of JS templates

Basho evaluates a pipeline of instructions left to right. Instructions can be JavaScript code, reference to an external JS file, or a shell command. To evaluate a JavaScript expression, use the option -j. Let’s start with a single item in the pipeline, a JavaScript constant.

# Prints 100
basho -j 100
