(You should ask your question explicitly. Is your question "why doesn't this work?"?) This is nothing to do with how many elements an array can have, it has to do with what arguments the range operator can take. The range iterator is expecting a fixed-width integer, which means that it probably will only work with numbers up to around 2**31-1. But you probably shouldn't be using ranges that big anyway.
