give below template struct, how can I list the members x, y and z? I've tried something with OriginalType and TemplateOf but no luck... it seems if I do foo!"str1" the "str1" became "part of type"? give .stringof from typeof(__traits(getMember, foo, field)) I thought the type would be foo!string or something.

You want std.traits.isInstanceOf:

    static if(!isType!m && isInstanceOf!(foo, typeof(m)))
