var from = require('from2-array')
var through = require('through2')
var cascade = require('cascade-stream')
// create a stream for a single letter
function createLetterStream(letter){
return from.obj([1,2,3].map(function(num){
return letter + ':' + num
}))
}
var source = from.obj(['a', 'b', 'c'])
var pipeline = cascade(function(chunk, add, next){
add(createLetterStream(chunk))
next()
})
var sink = through.obj(function(chunk, enc, cb){
console.log(chunk);
cb()
})
source.pipe(pipeline).pipe(sink)
