Indeed, I missed the output for find! A warning would definitely be helpful.<p>I like that you have users and thus will be able to test things out and get some genuine feedback.<p>This might however introduce a bias guiding your language and standard library in a certain direction (I think it&#x27;s inevitable and what&#x27;s happening in all languages anyway) .. Therefore I would add some of your peers into the mix.<p>Otherwise I really like the directions you are exploring, as I&#x27;ve come to very similar conclusions at this point in my career:
- being able to modify a system through safe additions
- not focusing too much on local details of a system
