map enum to field offsets (or create enum from field)

typedef Person = (
    string^ first,
    string^ last,
    string^ address,
);

// alternative 1: create enum from struct (or map it)
typedef FieldType = enum for Person;
typedef FieldType = enum int for Person;
typedef FieldType = enum int (first, last, address) for Person;

// alternative 2: array that maps things to field offsets
(string^, fieldof(Person))#[] fieldMap = [
    ("First name", :first),
    ("Last name", :last),
    ("Address", :address),
];
