During the YCP Killer project, Y2R didn't translate most YCP operators and builtins into equivalent Ruby constructs but into library calls. This was necessary to preserve behavior in various edge-case situations, mostly when nil was passed around. The resulting code is often long and hard to work with.
Example from SlideShow.rb:
I want to get started with developing apps for phones and tablets. It is a very general idea, rather open ended.
To have tangible results, I want to make a trivial app and publish it in the official Google Play store: Just Roll One Die.
