A modern programming language that makes developers happier.

kotlinlang

There is <https://github.com/PaulWoitaschek/Slimber> library. Readme states "no-cost-effect" for non-debug mode, but I can't understand how/why it works. As I can see it rely on `ifPlanted` function as an optimization helper, which in turn rely on `Timber.treeCount() != 0`. But `treeCount` (i.e. `ArrayList.size()`) is not a constant value, and compiler cannot be sure which value `treeCount` will have at runtime to eliminate anything.
