There is also more room to add formal validation so we could have
class AnotherStruct {
      readonly string(64) $firstName;
      readonly string(64) $lastName;
      readonly ?int(0-150) $age = null;
}

Although I would perhaps expect in this case to have 'date of birth' as 
'immutable' while age is something that will be variable.
But isn't all this just mainly another class object. As has been 
suggested for an improved array object but never developed further? 
Create an extension to support it first, although the validation element 
is still needed for any variable across the board ...
