=========
import std.meta;

template Parent(T)
{
    alias Parent = AliasSeq!(__traits(parent, T))[0];
}

unittest
{
    class A(T){}
    static assert(A!int.stringof != Parent!(A!int).stringof);
 }
=========

yields: Error: static assert  ("A!int" != "A!int") is false


the longer form

=========
import std.meta;

template Parent(T)
{
    alias Parent = AliasSeq!(__traits(parent, T))[0];
}

unittest
{
    template B(T){class B{}}
    alias T = B!int;
    static assert(is(T));
    static assert(T.stringof != Parent!T.stringof);
}
=========

yields: Error: static assert  ("B!int" != "B!int") is false

 too.
