Tables in Lua may contain both ordered (numbered) and unordered (named) members.  Most of the time, you'll use just named elements, or just numbered elements, but there are surprisingly frequent occasions when it's useful to use both.   You then need to remember if you iterate through members that ...

- #tablename will only go through numbered elements, and will give you nil if there's a gap in the numbering

- pairs will take you through all elements with non-nil values, but won't give you any members which are explicitly or implicitly set to nil

- ipairs will start at the element numbered 1, and go up through numbered elements until it reaches a nil, at which point it will go no further.
