The attached file is my first attempt at doing this in D.  It just
tries the mpl::set translation; however, I'm getting:
<--------- cut here -----------------
set_proto.d(59): Error: cannot implicitly convert expression 
((has_key_tester)(cast(set)(set_int_float))) of type 
set_proto.bool_!(false).bool_ to set_proto.bool_!(true).bool_
 >--------- cut here -----------------
Could someone show how to do this in D?

TIA.
