That only works for modules and types - Luís mentioned that 
__traits(identifier) only returns the type, not the identifier. 
Consider:

module foo;
import std.traits;

struct S { int n; }

unittest {
     S s;
     // Prints "s.n"
     pragma(msg, s.n.stringof);
     // Prints "foo.S.n".
     pragma(msg, fullyQualifiedName!(s.n));
}

As for getting the name s.n inside a template, I don't think 
that's currently possible.
