Inspired by @kees and @bagder I graphed #ArkScript source code age (last 3.x version is from mid 2023 hence the big purple triangle starting in 2023)

There seems to be a lot of code, but tests are counted too.
16'540 lines for the source code only, and 12'430 for the tests (8k dedicated to the fuzzing corpus, 4k for the unit tests)

I attribute the big jump to my recent "add tests everywhere" addiction
