You mean, the literal string name of the original symbol you 
passed as an alias? If so then you want the .stringof property.

void main () {
	int first;
	bool second;
	string third;
	
	mixin Foo!(first, second, third);
}

mixin template Foo(alias abc, alias def, alias ghi)
{
	static assert(abc.stringof == "first");
	static assert(def.stringof == "second");
	static assert(ghi.stringof == "third");
}
