Suppose you want to make a small, hackable interpreter, so you write an AST walker. Could you recover performance by supporting lightweight threads that use all the CPUs? The Python GIL preferred single threaded performance over multithreading, this is the opposite.

TIL that coreutils has a lightweight version of the `finger` command, appropriately named `pinky`!

One remarkable aspect of the JS packaging ecosystem is that people package individual functions. For example, lodash.sortby: https://www.npmjs.com/package/lodash.sortby It shows how lightweight the packaging process is. I've not seen this happen in other ecosystems.
