I really appreciate traits and what they are introducing into the process. I'm curious how I can iterate over all fields of the structure (s.tupleof pretty much works for that) and properties while ignoring methods and sub data types that defined inside of structure (they defined only as type, not the field but of course they got into __traits(allMembers, S)). The idea is to use foreach to easily print into console something like:

fieldNameA: fieldValueA
fieldNameB: fieldValueB
...
propertyNameA: propertyValueA
...

You can use .tupleof and __traits(identifier) for this.

Would it work with:
@property int propertyNameA()

And how to get key names then? As I remember tupleof return tuple of fields only, at least what I got how it works.

No, for that you need the traits getFunctionAttributes [1] (I think all functions are returned) and getFunctionAttributes [2].

You index the tuple and use the "identifier" trait.
