relates to:

• SR-3092 Function-level nested types cannot conform to Equatable

Issue Description:

Attempts to conform to comparable fail, when the class declaration is nested within a test.

func testA() throws {
        
        final class Property: Comparable {
            
            let id: UUID
            let address: String
            let date: Date
                        
            static func < (lhs: Property, rhs: Property) -> Bool {
                lhs.date > rhs.date
            }
            
            static func == (lhs: Property, rhs: Property) -> Bool {
                lhs.id == rhs.id
            }
        }

        // test stuff here
}

Type 'Property' does not conform to protocol 'Equatable'.  
Type 'Property' does not conform to protocol 'Comparable'.

If I cut and paste the property class code to a global scope, it works fine.
