Just to note, member function pointers are delegates in D, which 
combines the 'this' pointer of the object and a context pointer. Since 
the object is available at run time, such a delegate cannot be used as a 
template parameter.

partial is designed to work with free standing functions. It uses the 
second template argument as the first parameter to the function. So, 
there is no consideration for member function calls. Perhaps partial can 
be improved to handle that case but I don't know whether the 'this' 
pointer can be added to the delegate easily or at all.
