Please correct me if I'm wrong:

* if table has holes you don't know what # will return (it might return proper length or lenght of the first 'block' up till the first hole)
Do I understand this properly?

You missed one:
... or the last index of any fragment
[...] 

Then there is absolutely no way to check if the table has holes, except by iterating through the whole table.

So if you didn't create that table, you shouldn't use # on it.

I think I finally understand why everyone is so agitated by this issue. 

From a lua-newbie perspective, I think that it would be logical to have # throw an error when it can't return 'proper' length.
