Another little eero ReactiveCocoa example. This one is from one of the official examples from GitHub.

	// Only log names that start with "j".

	// Objective-C version...

	[[RACAble(self.username)
	filter:^(NSString *newName) {
	return [newName hasPrefix:@"j"];
	}]
	subscribeNext:^(NSString *newName) {
	NSLog(@"%@", newName);

Trivial example of using ReactiveCocoa with Eero.

	#import <Foundation/Foundation.h>
	#import <ReactiveCocoa/ReactiveCocoa.h>

	interface Reactive

	property (retain)
	String name
	String address

	registerProperties

A snippet of code showing "global dot-notation" for Eero message sending (currently under evaluation).

	parseQueue = OperationQueue.new

	NotificationCenter.defaultCenter.addObserver: self,
	selector: \|addEarthquakes:\|,
	name: kAddEarthquakesNotif,
	object: nil
	...

	self.parseQueue.addOperation: parseOperation
	parseOperation.release // once added to the NSOperationQueue it's retained, we don't need it anymore

Eero supports (as an experimental feature) 'instancetype' for method parameter types. Inspired by Jonathan Sterling's blog: http://www.jonmsterling.com/posts/2012-02-05-typed-collections-with-self-types-in-objective-c.html



	protocol OrderedCollection <FastEnumeration>
	at: UInteger index, return instancetype
	put: instancetype object
	end


	protocol MapCollection <FastEnumeration>
	at: id key, return instancetype
