Sorry, I wasn't quite clear:
The culprit is in the line
local newset,cloneset={},set
which is doing a multiple assignment on the locals newset and cloneset.
You probably ment to say:
local nweset
local cloneset = {}
local set
but what your code does is:
local newset = {}
local cloneset = set
f() removes all entries from cloneset, which is a now a reference to a,
thus leaving the table a empty.
Coming from C this one is indeed tricky, I admit it happend to me a few
times as well.
