How does it currently know what type something is? If you define
something using an enum, how is PyCharm going to know what the members
of that enum are?

That's *one of* the things you can do with an enum. There are many
other features of enumerations, and I'm trying to boil your idea down
to its most compact form. You don't need all the power of Enum - you
just want to be able to list off the valid options.
