/// @assertion We say that a type T0 is a subtype of a type T1 (written
/// T0 <: T1) when:
/// 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 and named fields

/// @description Check that if type T0 is a subtype of a type T1, then instance
