The point was that if there's a certain coding pattern that can be accommodated by adding a new language feature, it is worth considering. The fact that it's readily doable with some effort in some other way is not an argument against it.
C++ started as a reasonable extension to C, but now it's just something else (nor does it even want to be seen related to C now anyway). Extending C with something new, without rushing, is a perfectly fine idea.
