Hello everyone! I'm loving the new Playground pages feature! The only issue I found so far is that - apparently - I cannot refer to anything declared in another page. Shared sources are all right, but wouldn't work for what I'm trying to do: I want to explain a topic in one page and build on top of that in the following page.
For example, assume you're teaching Algorithms, you might want to have a page that explains Queues and Stacks. In another page you might want to explain the BFS algorithm to traverse trees and graphs. To implement BFS you need a Queue and of course you'd like to reuse the implementation you wrote in the previous page. As far as I can see playing with the first beta of Xcode 7 (7A120f), this isn't currently possible. It seems that every page is a self-standing playground and they just happen to be bundled together.
Am I right or is there a way to reference classes, structs, etc. from one Playground page in another page in the same Playground? If not, is it a feature we can expect by the time Xcode 7 comes out of beta?
