Can you explain what you mean by "having used Lua a lot, the indexing issue just goes away"? Most modern languages have facilities (iterator combinators) that make indexing less common than e.g. in C, but in my experience, you can never completely escape indexes, and for the indexes that I do have to deal with, I really want half-open intervals and 0-based indexing.
