I haven't tried this, but:
function insert(loc, val)
local last = 0
local tbl = _G
for match, _, pos in string.gfind(loc, "(.-)(%.)()") do
last = pos
if not tbl[match] then tbl[match] = {} end
tbl = tbl[match]
end
local match = string.sub(loc, last)
if match == "" then
tbl[table.getn(tbl)+1] = val
else
tbl[match] = val
end
end
