I got curious re. your \"primitive Functional\" at my-little-pony.html#/7/4, and just pasted your 4 lines into an existing fibo.pony file I had. When trying to compile, I got things like this:\r\n```\r\nfibonacci/fibo.pony:7:38: couldn't find 'add' in 'None'\r\n  fun fib(n: U64): U64 => fib(n - 1) + fib(n - 2)\r\n                                     ^\r\n```\r\nIs there some way to supply the missing 'add', or was this just some \"fantasy\" example?"}}
