I have no clear view about \set yet. It would seem to me that
\unset
should be equivalent to \revert, and \set should be equivalent
to
\revert+\override.
As we are contemplating a major change anyway, I'd
prefer an equivalence in operation of \override,
\once \override and \revert with \set, \once \set
and \unset. Or is this infeasible?
A sequence of \set \set \set would lead to stack buildup. That
seems
contrary to the spirit of the command name.
On the other hand, a sequence of \set \unset will, under my
proposal
which is pretty much the current semantics, cancel a previous
override,
while a sequence \override \set \set \set \revert will be neutral,
all-in-all.
Now I am confused. Are you saying that \set will
operate on grob properties rather than or in addition
to operating on context properties? That would be
a major change!
