I actually would have preferred an error message. Something like "bash: test: missing array index" would have been clear enough for me. The current behavior is absolutely mystifying for most people. I'm not actually requesting a change. I recognize that it's far too late for that. Hmm... If at some point you choose to add a shopt that turns on extra warnings, I'd love it if *this* could be included in said warnings. The use of an array variable with no index, having index "0" be chosen for you, is worthy of a warning, in such a hypothetical mode.
