Hello,
If I try:
\def\test{test}
\afterassignment\test \advance\count0 by2
then \test is processed immediately after the \advance command. But
if I do:
\afterassignment\test \toksapp 0{xx} \the\toks0
then \test waits to another assignment than \toksapp. It means, that
\toksapp <toks> (and friends \gtoksapp etc.) is not assignment. Is it
an intention or a bug?
it's intention ... these prepend and append things are a command class
on their own which is why we have explicit g and x variants
I respect the intention but I don't understand your argument. The \def
is a command on its own too, it has explicit g and x variants and _it
is_ assignment.
After \tracingall we can see {changing \toks0=} {into \toks0=xx} which
is similar report as {changing \m=undefined} {into \m=macro:-> xx} when
\def\m{xx} is traced.
