Whoops, a bit quick on the draw.
There are of course also set_intersection and cset_intersection,
but not AFAICS any method for `&`.

Unless I'm missing something, I don't see any method
in pkg:sets for intersection other than gset_intersection.
So you're using the base R function `&` whose help page
tells you that its arguments should be vectors. Yours
aren't.

When using generalized sets from "sets" library
A & EMPTY does not work, but gset_intersection(A,EMPTY) works: example
code below
Is it a bug?
Best regards,

support <- universe <- c('a','b','c','d')
A <- gset(support=support, memberships=c(0.2, 0.2, 0.9, 0),
