Right. Actually most of the time that function would work for me.
But I wouldn't know what to call it. Does it exist in other languages?
I don't think copying the table before is a good idea performance-wise,
especially on PUC Lua: https://gist.github.com/catwell/7564258
The LuaJIT version could probably be made faster by pre-allocating
the tables. I used 2.0 so I didn't have table.new handy.
