feature request: expose stream object in es.map

[cambridgemike]

It would be nice to call this.emit('myEvent', data) from within .map().

[anko]

That sounds like a very leaky abstraction; if you're calling emit multiple times inside a map, it's not a map anymore. What's wrong with es.through?

@cambridgemike sorry, am not adding new features. and @anko is correct that you can easily do that with through.
