Tempated class instantiation

[Mike L.]

I'm making a class template that only works with strings, so I thought it'd be 
good to instantiate each template with char, wchar, and dchar right in the 
template's module so that when it's compiled it'll be part of the .obj file and 
won't have to compile it for every other project that uses it. However, I get 
an error reproducible with this:

module test;

class A(T)
{
        version(broken)
        {
                class B
                {
                        T blah() { return t; }
                }
        }
        
        T t;
}

mixin A!(int);

int main()
{
        A!(int) a = new A!(int)();
        return 0;
}

If what I want to do makes sense, how should I be doing it?
