Example

import { periodic } from 'most'
import { proxy } from 'most-proxy'

// create a proxy
// returns *attach* to attach proxy to another stream, and a proxy stream *stream*
const { attach, stream } = proxy()

// observe the proxy, taking only three events
// proxy is a real most.Stream
// when stream ends, original will also be disposed of internally
stream.take(3).observe(x => console.log(x)) // 1, 2, 3

// here we create the stream we want to use as the circular dependency
const original = periodic(100, 1).scan((x, y) => x + y, 0)

// pipe events from original to proxy stream
attach(original)
