%D Some expected plain variants follow. We don't reuse registers because we don't
%D want clashes. These will go away and packages that need them have to define
%D them.

%D A few registers used in traditional allocations that we don't need, so
%D these really go now:
%D
%D \starttyping
%D \countdef \count@   255 % hm, used in \newif .. todo: replace it there
%D \dimendef \dimen@     0
%D \dimendef \dimen@i    1 % global only
%D \dimendef \dimen@ii   2
%D \stoptyping
%D
%D A waste of space ... so \type {\suggestedalias} can also go away:
%D
%D \starttyping
%D \suggestedalias \count@   \scratchcounter
%D \suggestedalias \dimen@   \scratchdimen
%D \suggestedalias \dimen@i  \scratchdimenone
%D \suggestedalias \dimen@ii \scratchdimentwo
%D \stoptyping
