• In ECMAScript, ?. is called "optional chaining", and in Kotlin is called the "safe call operator".
• I also could have used the ECMAScript ?? nullish coalescing operator to be more precise in my undefined handling than what I was doing with ||.
• As in any other language, I could have created structured optional and result types in TypeScript to mimic those of Rust, but I opted for the simpler unwrapped method here.
• In Zig and Odin, I gave a poor analysis of wrapped optionals and failable results. One improved analysis would be to see where nesting is possible. For example, can a nest one optional inside another, or do the idiomatic language features not support this?
• In Odin, I could have used a distinct string for my error type rather than putting it inside a struct, but I liked seeing the extra context in the output that I got from the struct.
• In Kotlin, the "never" type is called Nothing.

Quote of the day

From the NeverValued Story:

A null would be something. Nah, this was Nothing.
