| /// A record type A is a subtype of record type B iff they have same shape and |
| /// the types of all fields of A are subtypes of the corresponding field types |
| /// of B |

| /// @description Check that if type T0 is a record with the same shape as T1 |
| /// and the type of each field of T0 is a subtype of the corresponding field |
| /// types of T1 then T0 is a subtype of T1. Check positional fields only |
