Public Interface Comparable Extends Equatable

An order: what < says, which the other comparisons follow unless a type gives its own.

Examples

Struct Version Implements Comparable
    Field Major: Int
    Field Minor: Int

    Operator <(a: Version, b: Version): Bool
        Return a.Major < b.Major || a.Major == b.Major && a.Minor < b.Minor
    End Operator
End Struct

Expect(Version(1, 2) < Version(1, 10))
Expect(Version(2, 0) >= Version(1, 9))
Expect(Max(Version(2, 0), Version(1, 9)).Major == 2)
