take symbol as parameter

[Marc via Digitalmars-d-learn]

how do I take a symbol as parameter?

for example:

template nameof(alias S) {
        import std.array : split;
        enum nameof = S.stringof.split(".")[$-1];
}

Works fine for say a enum member such nameof!(myEnum.X) but this:

        struct S { int v; }
        S s;
        writefln(nameof!(s.v)); // should return "v"

return the following error:

Error: template instance nameof!(v) cannot use local 'v' as parameter to > non-global template nameof(alias S)
