Use inline/value class instead of primitive type on the data class properties declaration

[radityagumay]

As we use primitive type on the data class properties declaration it would give a high chance for error-prone of doing substitution in between properties. Indeed naturally we're able to avoid this issue by declaring the name of the properties themselves when assigning the value. However, it still has a chance the users do not follow the convention for doing that. The consideration for using the inline/value class can be helpful here.
