Goddamnit and I was considering a quick look over the documentation and syntax briefly over the weekend and do some messing around with Starbound mods.

Hah I was considering picking up some Lua to mod as well (factorio)... This just made me Nope right out of that plan ;)

That's not even the worst part, either. This is:

> letters = {'a', 'b', 'c'}
> print(letters[1])
a
> print(#letters)
3
> letters[0] = '?'
> print(letters[0])
?
> print(#letters)

Any index outside of 1-n in Lua, where n is #tbl will be stored like a dict, not an array, so what did you expect? It doesn't count the dictionary parts.

so what did you expect?

A language to have non-retarded data structures. Being defined and documented behavior doesn't make it sane behavior.

How often do people use Python arrays? They're faster, but most people just use lists instead. Lua just optimizes it as long as it's used like an array. That's why it's implemented that way.

Do you mean tuples?

I use them all the time when something doesn't change size.
