Would the following be possible?

/* snip */
template Foo(T) {
     this() {
         // init? registration? factory work? etc
         // called on first use of 'Foo!(bob)' for each different 'bob'

This is why I ask silly questions.  Knew there had to be a way for it. 
Danke.

Now I assume then that if I had a class defined as:
class Foo(T) {
     this(char[] arg) {
     }
}

That I would instantiate in the obvious way:
void main() {
     Foo!(int) x = new Foo!(int)("arg");
}

And that I could freely use 'Foo!(int)' as a static reference.  If so, 
its all sweetness.

Maybe, the following is what you want.

class Foo(T) {
    private static T _bar;

    static this() {
        // initialize _bar
    }
    static ~this() {
        // finalize _bar
    }
    static void baz() {
        // use _bar
    }
}

int main() {
    Foo!(int).baz();
    return 0;
