Another #Lua observation: I had gotten in the habit of using the #Python #JSON library for storing and reading small amounts of data. I'm quite set on switching over to #LuaLang wherever I used Python before and it's so nice to just write my database files in the same language as the code itself.
I'm aware I could write my data as a Python script and import it, but this felt less natural than the analogous construction in Lua. This is probably because Lua is an extension of SOL, a language for describing data.
All the little conveniences like not having to put quotation marks around string keys and being able to assume an unassigned key is nil are really pleasing me, too.
