No. I'm playing around with the possibility of having similarly behaved
functions like lattice.options() and lattice.getOption(), and I was
checking the behaviour of options() when I encountered the segfault.
Should options( mylist ) work at all? It's not documented, at least not
in ?options. Is that a documentation oversight?
