take(x) 'takes' nothing when emitted exactly x elements

[salty-horse]

This is a modified example from the readme.txt:

var Lazy = require('lazy');

var lazy = new Lazy;
lazy
  .take(4)
  .join(function (xs) {
    console.log(xs);
  });

// OK when there are five elements. Prints nothing when there are 4
[1,2,3,4].forEach(function (x) {
  lazy.emit('data', x);
});

I wonder if it's because you never sent 'end' event?

[salty-horse]

lazy.emit('end') after the 4 'data' emits doesn't seem to help.

Frankly, I'm new to node and its conventions, and the Lazy documentation seems to assume some background knowledge.
If you don't think it's a bug, maybe you could clarify how Lazy behaves with events?

[pkrumins]

It's a bug then! I'm gonna fix it.

re events: basically lazy eats 'data' events and terminates processing when it receives 'end' event.

[salty-horse]

Correction: emit('end') works. Sorry :/ (I probably forgot to save the file before testing)

Just to understand, why does take(x) have to wait for an 'end' if it already received x elements?
