Isn't Record<EnumType, whatever> working?

Then instantiate like:

``` { [EnumType.First]: ..., [EnumType.Second]: ... } ```

Yep, do this all the time. It's also really nice because when you define a type as

    Record<EnumType, any>

then when you are creating an instance of that Record object, it requires a key for all the EnumType values, and will fail if you forgot one. Still possible to do

    Partial<Record<EnumType, any>>

if you want the keys to be only of the EnumType, but don't require all the EnumType values to be used as a key in the Record.
