Enum TagKind 

pub enum TagKind {
    Struct,
    Union,
    Enum,
}

Which keyword introduced a tag.

Kept because the three do not interchange, and because the diagnostic for using the wrong one has to name what was declared. Whether a mismatch is an error is semantic analysis’s call; the parser only records what it saw.

Variants

Struct

Union
