module runnable;

import std.stdio, std.traits;

struct foo {  struct bar { static int baz;} }

template Test(alias arg)

    pragma(msg, fullyQualifiedName!arg);

void main()

}

That gets the types foo, bar, baz. I wanted the identifiers. 
Something like this:

struct Parent
{
    Son son;
}

struct Son
{
    int value;
}

void main()
{
    Parent parent;
    alias t = Magic!(parent.son); // t is now parent (not 
Parent)
}

thanks that's clear now... it's indeed not possible

template Test(alias arg)
{
    // challenge: get "foo.bar.baz" here...

{
    alias t = Test!(foo.bar.baz);
}

Maybe something with opDispatch but it sounds complicated at 
first glance.
