struct S {
  int i;
}

is( typeof(__traits(getMember, S, "i")) == int ) // works

The spec, on the other hand, says it cannot be used on non-static fields. That's my interpretation.

No, the error is in the assignment:

struct S
{
    int i;
}

void main()
{
    __traits(getMember, S, "i") = 1;
}

Error: need 'this' to access member i

The trait docs specifically state that all the trait does is forms an expression.

But I don't think we even need it anymore since we can use string mixins, although it has to be around for backwards-compatibility.
