And without "abusing" (IMHO ;-)) foreach

where(
  a!forEach(
    items: {"a", "", "b"},
    expression: a!isNotNullOrEmpty(fv!item)
  )
)

a!forEach(
  { "a", "", "b" },
  if(isnull(fv!item), {}, fv!index)
)

How?? I can see foreach getting used.

where(if({ "a", "", "b" } = { "" }, false, true))

I think this one is "without abusing" foreach.
