During my last post, I claimed all that was needed was to add the ability to my Transpiler to emit nested and anonymous classes, and by now I expected to be done with that. It turned out that what I though was a "good enough" Transpiler, was in fact, not.
Sometime between version 1.5 and 1.7.10 of Minecraft, the source code has undergone significant refactoring and made use of previously unused Java features, in particular, Nested and Anonymous classes, making my transpiler no longer "good enough" and thus needing to be improved.
