Re: The real problem with vectors and Lua

["Dylan Cuthbert" <dylan@...>]

Browsing through the python documentation, I found that they have
implemented pretty much exactly what I am talking about:

http://www.python.org/doc/current/tut/node7.html#SECTION007300000000000000000

What's really nice is the "packing" and "unpacking", ie.
frog = 10, 20, 30    -- packs frog with 3 numbers
x, y, z = frog  -- unpacks frog into its 3 separate elements

These tuples are *immutable* sequences, ie. they are constants.

Lua would benefit greatly from this kind of feature.
