What do you mean by "everywhere?" I'm a bit confused. When I read your
original email, I thought you were talking about changing command line
argument parsing for places where version numbers matter so that _ and
. were interchangeable. Then Doug brought up std::tuple, and now
you're talking about availability attributes. A bit more detailed
scope information about what you are proposing would be useful. :-)
