Your various types of properties look interesting, and I definitely 
think that indexable properties are definitely a neat idea.  However, 
there are two issues that I think could be improved.  First, it would 
not appear that you support write-only properties.  Second, it appears 
that your set type is fixed, meaning that if it is possible to assign an 
A to a B, it may not be possible to assign an A to a B property.  Mine 
avoids this problem by templating the set method to take any type, 
allowing compilation to fail if the type client code attempts to use is 
invalid.  I could be incorrect in my assessment of your code, as I have 
not compiled it myself, so please correct me if I am wrong.
