% We renamed all primitives to \cs[no-index]{tex_\ldots{}:D} so all
% others are deprecated. In \pkg{l3names}, \cs{__kernel_primitives:}
% is defined to contain \cs{__kernel_primitive:NN} \cs{beginL}
% \cs{etex_beginL:D} and so on, one for each deprecated primitive. We
% apply \cs{exp_not:N} to the second argument of
% \cs{__kernel_primitive:NN} because it may be outer (both when doing
% and undoing deprecation actually), then \cs{@@_primitive:NN} uses
% \cs{tex_let:D} to change the meaning of this potentially outer
% token. Then, either turn it into an error or make it equal to the
% primitive~|#1|. To be more precise, |#1| may not be defined, so try
% a \cs[no-index]{tex_\ldots{}:D} command as well.
