Exactly!

We should refrain from adding extensions to C or C++ from a
short-sighted point of view. At any point we n eed to have the picture
in the foreground, or else we would end up in one or two years cursing

Well, in the C++ front-end there is no reason we should be creating
that artificial typedef all around: it wastes memory and unnecessarily
complicates routines.
