Iteration over structure fields and properties

[Void-995 via Digitalmars-d]

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
...
