Re: turning a table into a list?

[Tobias Käs <tobias.kaes@...>]

>From the manual / basic library:

unpack (list)
Returns all elements from the given list. This function is equivalent to
  return list[1], list[2], ..., list[n]

except that the above code can be written only for a fixed n. The number n
is the size of the list, as defined for the table.getn function.


It looks like you cannot write it yourself with a variable size of the
table.
However you can use unpack since it does what you want anyways.
