Cheers, a new version of Mirror library, with quite a few changes, is available both in the sandbox and in the vault. Important changes in this version: - added two functions; for_each and reverse_for_each working with meta_class<>::attributes, meta_class<>::all_attributes and meta_class<>::base_classes, which allow to call a functor for every member attribute and base class of a reflected class. - added at and size algorithm working with attributes, all_attributes and base_classes of a meta_class<> - removed the original for_each static functions from meta_class::attributes and meta_class::all_attributes - updated existing examples to show the new functionality - added an 'alpha' implementation of meta_class traversal that 'guides' a custom visitor through the structure of the reflected class. Two versions ('deep' and 'flat' traversal) are available. - added a new example showing traversal by a sample visitor, that is writing out XML-like info about the given class to stdout, with several elaborate classes. any comments are welcome.
