Oops. This is what I get for happily writing code without testing it.
Where I called "table.merge" I should have called "list.concat":
-- @func list.concat: Concatenate two lists
-- @param l: list
-- @param m: list
-- returns
-- @param n: result {l[1] ... l[table.getn (l)], m[1] ...
-- m[table.getn (m)]}
function list.concat (l, m)
local n = {}
for _, v in ipairs (l) do
table.insert (n, v)
end
for _, v in ipairs (m) do
table.insert (n, v)
end
return n
end
