- Switch to a fairly standard code format. This is largely based on
IntelliJ defaults, with some minor tweaks applied via editor config.
Should mean people don't need to import a config!
- Use "var" everywhere instead of explicit types. Type inference is a
joy, and I intend to use it to its fullest.
- Start using switch expressions: we couldn't use them before because
IntelliJ does silly things with our previous brace style, but now we
have the luxury of them!
We now fuzz UploadFileMessage, generating random files and checking they
round-trip correctly.
The joy of having a long-lasting refactor branch with an absolutely
massive diff, is that you end up spotting bugs, and then it's a massive
pain to merge the fix back into trunk!
