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.

In Python I can choose any name for my instance variable when defining a method. In practice people almost always use `self`. Go has the same flexibility, but using other names for the instance is totally normal!

Multihash is a rather nifty format for hashes, where you can distinguish between e.g. a SHA1 and a Blake2b: https://multiformats.io/multihash/ It originates from the IPFS project, where they want flexibility in how they implement content-addressable storage.
