Can't Iterate over ARGV or HGETALL results in Lua scripting

[NimrodParasol]

When using eval to run Lua script, when iterating over ARGV using the following code:

for i, v in ipairs(ARGV) do
end

An exception is thrown:

E   IndexError: list index out of range

The code is working just fine against a real Redis.
Look like it happens due to ARGV being POBJECT (a Lupa's type?) instead of a regular Lua table.

The same happens when trying to iterate over the results of redis.call('HGETALL', key)

Thanks for the report. I don't know much about Lua myself, so the only way this is likely to get fixed is if someone (such as yourself) can contribute a pull request.

@NimrodParasol I'm assuming that this is fixed by #208 and #209. If not please re-open.
