# Promising Future
A glimpse of a promising future in which ruby supports delayed execution

## Overview

    require 'promise'
    require 'future'    # can just require future if using both

    x = promise { 1 + 2 }
    y = future  { sleep 10; 5 + 5 }

    puts x      # => 3
    # ... do work for 5 seconds
    puts y      # => 10, after blocking 5 seconds

Promises and futures both transparantly delay the execution of a block.
Futures run the evaluation of the block optimistically in another thread.

Note that this is pretty useless in irb, which will evaluate everything
as part of its read-eval-print loop.
