I also share your belief that using function-style accessors rather than assignment is preferable.
Why? What does that syntax offer you that makes it better? I understand Gennadiy's notion of searching for ".value" allowing him to find cases in which he assigns to a "property," though I fail to understand why such a search is important. I don't understand how parentheses help anything.
In your code, you seem to support both syntaxes:
std::string strName = Z.Name(); int iCount = Z.Count; Z.Count(3); Z.Count = 6;
I see nothing gained by using parentheses.
see my previous mails for arguments in favor of accessor functions, but if people don't agree with that, at the very least both syntaxes should be supported, because interfaces using properties and interfaces using accessors can overlap. take for example a GUI library that uses your proposed properties. a GUI "list" widget would probably make its list elements available through the interface of a STL container, so it must support size(). but you'd probably also want a property named "size", if that is how the rest of the GUI library is designed.
