On the other hand, the advantage of the glacial pace of change in the C standard is that the language hasn't been ruined yet. One of the most important tasks of the committee should be to say "no", even if that's not a popular thing to do. The right place for experiments in the C ecosystem is outside the standard, in libraries and language extensions.
The C++ committee says "no" overwhelmingly more often than not. That is much of what Izzy was complaining of.
Izzy got more stuff into C++ than 99.99% of others who tried. Ze spread zerself too thin pushing too many things. It is a major achievement to get one thing in.
