Hi,

I am using simple class properties facility for some time and found it quite useful. Actually it's nothing fancy - simple helper classes to eliminate repetitive setter/accessor methods (and no need for language extensions).

Have you had a look at SC22/WG21/N1615 (C++ Properties -- A Library Solution) by Lois Goldthwaite (http://std.dkuug.dk/jtc1/sc22/wg21/docs/papers/2004/n1615.pdf)?

Yes. And in a future we may swith to implementation based on that. But I wouldn't say this use case prove need for the language extension. These templates is a counter example. Gennadiy.
