Today I learnt that Lua projects often use *3* spaces for indentation! https://github.com/luarocks/lua-style-guide/blob/master/README.md#indentation-and-formatting I initially thought something was very wrong with editor config.

Playing with optional type signatures in Python, I realise that the return type is the most important to me. I'd much rather have a function with only a return type instead of a function with only parameter types. It's often quick to add too.

TIL Rust has an ambiguity `if Foo {}` -- is `Foo` a value of type bool, or a struct? Rust solves this by defining a grammar production 'any expression except struct literals' and using it in this position. https://rust-lang.github.io/rfcs/0092-struct-grammar.html
