 Inline classes behave differently compared to regular classes.
 They are represented both as the underlying values type and as a wrapper.
 Hence, they do not have a stable identity.

 Inline classes are a tool to allow developers to define value-based classes to provide this behavior.
 
 ## Declaration

 The inline classes force to initialize a single property in the primary constructor.
