 A lot of Objective-C methods return void, especially within Cocoa. This
 makes a lot of sense for a language like ObjC, but not nearly as much for
 Ruby, since all methods have a return value. Since method chaining is one
 of the things that make Ruby so elegant, I propose that all ObjC methods
 that are declared to return void actually return the receiver instead.

 This will allow for method chaining such as

 {{{
 if someNSTask.launch.waitUntilExit.terminationStatus == 0
   # …
 end
 }}}

 which would otherwise have to be written as
 {{{
 someNSTask.waitUntilExit
 someNSTask.launch
 if someNSTask.terminationStatus == 0
   # …
 end
 }}}

 .
