if onlyarray then
if t_k == "number" and k >= 0 then
if k >= high_n then
high_n = k
seen_n [ k ] = v
end
else
onlyarray = false
end
end
the code above deals array in to_bson in bson.lua, array value will store in seen_n only if k >= high_n, however this condition won't always be true. It means we may lost some value and results in 'null' stores in mongodb.
I think seen_n [ k ] = v should be moved out of the if condition and we can hold all the data.

As we know, when we iterate table with pairs in lua, it doesn't guarantee the order as we defines in table. http://www.lua.org/manual/5.2/manual.html#pdf-next
