[Programming in Lua](https://www.lua.org/pil/13.html) does a much better job at explaining metatables than I ever could, so take a look at how they use it. We're not going to use all the features they discuss, just 1: the \_\_index method, to replace the DeSerialize() function from @{tut030_inventories.md}. |
