I'm always a big fan of not changing something in a language unless it's 
REALLY necessary, given that it will cause old code to break.

After seeing the huge discussion of #, I personally wouldn't be caught dead 
using it. First of all, pairs() and next() can be used to iterate through any 
table, removing one of the main uses of #. If I must know the number of items, 
I can always have a "items" key with the count for a value. If I must know the 
highest integer subscript, I can always keep it in a "hi" key. If making a 
ring buffer, I can always use a "lo" key. I don't know, maybe there's a 
performance penalty for these things, but using a table of key->value pairs 
makes it very easy to keep track of things like this.
