Best Practices

What is going on with these comments? They are getting randomly deleted...

> Then let's be a bit more pragmatic and omit this strong Do Not Rule. Whenever someone will need to use an existing partial that somehow is tied to particular instance variables, they can refactor to the long form above. Don't add structure that you don't know you will be needing yet.

The point is: adding locals to partial calls will result in partials that will be immediately reusable, with a minimal change. If we know a choice leads inherently to better design then let's add it as a rule and worry about specific cases only afterwards, not the other way around.
