Enums

• enums are reasonably simple, they're just a known set of allowed values

• and are represent by their exact value

• no const enum needed?

• just integer and string enums..?

• auto incrementing enum (starts at 0, int64, signed)

• enums are nominal! need to explicitly cast

• enums are carried by their value, unlike unions / literals

• so int enums are actual ints, string enums are just managed strings

• like all nominal types enums may carry instance members, constants, etc.
