Are you sure? For me, it works in bash. Just tested under MacOS, Debian
Stable, and Ubuntu. It doesn't work in other shells which implement regexp
matching differently. For example, in zsh the matching array is called `match`
instead of `BASH_REMATCH`. However, the script is meant to be executed in bash
anyways and therefore has a `#!/usr/bin/env bash` shebang.
