%% title = "`None` or `Invalid` cases in enums are a bad idea"
% id = "01HCG7KTGGHWTT1ME9GQ5VPFPR"
- by having them, you're forcing your users into an API that forces them to think about the
invalid case every time they read the value.
% id = "01HCG7KTGGBJRX5JGQTFD59P4W"
- you're repeating the million dollar mistake - `null`
% id = "01HCG7KTGGYQ8EQB97AMFJPWYK"

to represent a possibly-invalid case
