are non-empty when T is an interface!

An interface cannot contain fields and yet these return non-zero and screws up my code. While I can filter for interfaces it makes me wonder what else may slip through?

Is it a bug or what is going on?

Can you provide code to demonstrate? I get no fields when I do this:

interface I
{
}

import std.traits;
pragma(msg, FieldNameTuple!I);
