This is true and, since this is strictly a runtime library,  
quantity<D,T> will just be
a T in memory, so a special reinterpret cast is probably not  
necessary...

As Andrey points out, conversion to T can be through the value()  
member function
and conversion from T via explicit constructor specifying the  
dimensions, so any
cast would be redundant. That said, I don't mind a little redundancy  
if it increases
transparency...
