lua table unpack

The unpack function in Lua allows you to pass all elements of a table as arguments to a function. When used, unpack returns the elements of the table starting from index 1 to the last non-nil value. This can be useful when you want to pass the elements of a table as arguments to a function that accepts multiple arguments. Keep in mind that unpack is not available in Lua 5.2 and later, so if you're using a newer version of Lua, you may need to use a different approach.
