teaser:
\def\ResetMyList{\lua{MyList = {} ;}}
\def\FlushMyList{\lua{tex.print(table.concat(MyList,","))}}
\def\AddToMyList#1#2{\lua{table.insert(MyList,#1,"#2")}}
\def\RemoveFromMyList#1{\lua{table.remove(MyList,#1)}}
\defineoverlay[mine-1][ONE]
\defineoverlay[mine-2][TWO]
\defineoverlay[mine-3][THREE]
\startsetups [test] \framed[background={\FlushMyList}]{it works okay}
\stopsetups
\ResetMyList
\AddToMyList{1}{mine-1} \setups[test]
\AddToMyList{2}{mine-2} \setups[test]
\AddToMyList{1}{mine-3} \setups[test]
\RemoveFromMyList{1} \setups[test]
\RemoveFromMyList{1} \setups[test]
\RemoveFromMyList{1} \setups[test]
but ... for at least half a year [we don't expect to have a stable user
interface before eurotex] you have to fall back on list processing
macros in syst-gen.tex and syst-ext.tex
(you can add to lists, split lists and reconstruct them using those
macros)
