True. Passing everything that the iterator produces seemed the cleanest way.

Other options are a "valseq" function to produce values or... use a filter:
function value(seq, f)
local saved_key
local function self(k, ...)
saved_key = k
return ...
end
return function(s, k)
return self(f(s, saved_key or k))
end
end
t = {
aap = "noot",
mies = "vuur",
wim = "jet",
}
for x in seq(pairs(t)) (value) do
print(x)
end
