I think, D is a typesafe language, therefore you can't use 
variables with no type declaration.

One thing you can search for, are templates but even there you 
have to define a type:

import std.stdio;

enum Category : string { first = "first"}

template Pair(T)
{
	T t;
	T cat;
}


void main()
{
	alias Pair!(string) a;
	a.cat = Category.first;
	a.t = "first";

	writeln(a.cat, " . ", a.t);
}
