I like the notion of "pac-man complete", the idea that your programming language needs enough effects/IO to do a 2D game: https://prog21.dadgum.com/23.html
We should have more levels of language capability. 'Can do Hello World' and 'can do fizzbuzz' are useful for a new language.

I'm trying to decide what program I should show on the home page of my PL.
Hello World is too simple to show much syntax. Fibonacci is OK but the reader may not know what print(fib(10)) should show.
Maybe print(greet("World")) is better? It gives you a function definition at least.
Playing with Claude and my new programming language has made me add features that it wants. I think they're reasonable.
`for method in methods` -- custom syntax error explaining that `method` is a reserved word
`echo 'println("hello world")' | garden` -- eval snippets from stdin
I'm coming round to the view that a main function shouldn't take arguments.
For example, in Rust you have to call std::env::args() to get CLI arguments.
This makes Hello World less verbose, and gives you more flexibility in setting up CLI argument parsers.
