Rather surprisingly, all the treeshake tooling is done in just about 2
hours of work. From now on it'll be easier to update stats.txt. Observations:

a) Binaries are tiny compared to conventional stacks. Tens of KB.
b) ~80% of binaries are tests and unused libraries in all my apps.
c) ~75% of LoC in SubX sources are tests or comments.
