That's pretty C-like, and I don't have any strong dislike of it, but I feel I should point out that users will need to quote the final argument if it contains square brackets, just like with unset 'a[i]'. Another choice would be a more shell-like syntax: declare -s size -A foo=(...) I'm curious whether the size has to be specified up front when the array is declared, or can be adjusted on the fly. The shell-like syntax feels more natural if the size is being adjusted, since you can write declare -s new_size foo without needing to specify the -A again. But it's not a huge difference.
