Maybe I'm wrong on that assumption.  Thinking more about it that might 
be just what is needed.  Assuming some EQ t = t^x you could do:

// this it total make believe...
quantity<temp> t = 5 * F;
quantity<nodim> x = 3.14;

t = pow(t, x) * temp() * F; // omit last part?

Worth thinking about anyway.
