Don't forget about templates (appear as members too, but don't have a type).
This will print all fields of struct/class S:
enum s = cast(S*)null;
foreach (i, m; s.tupleof) {
enum name = S.tupleof[i].stringof[4..$];
alias typeof(m) type;
writef("(%s) %s\n", type.stringof, name);
}
Real Programmers don't use std.traits. ;)
