I'm confused; are we talking about existing or desired behavior? The
following prints "3 3 3" in Lua 5.2, Lua 5.3 and LuaJIT for me and
this is what I'd expect:

print(#({1, 2, [3]=3}), #({1, [3]=3, 2}), #({[3]=3, [2]=2, 1}))

I'd expect #a to be 1 and this is how it's reported by Lua 5.1-5.3.

BTW, "({1,2,[2] = 0})[2]" is 2 in Lua 5.2 and 5.3, but is 0 in LuaJIT
(I tend to favor seeing 0 in this case).
